Buy vs Lease a Luxury Car

The luxury car category (Mercedes-Benz S-Class, BMW 7 Series, Audi A8, Lexus LS, Genesis G90, Porsche Panamera, Maserati Quattroporte) is the segment where leasing wins for the broadest range of buyers. Three mechanisms align: steep year 1 to 3 depreciation (35 to 45 percent of MSRP) that lessees pay for and walk away from, aggressive captive subvention that drops money factors below 1.5 percent APR equivalent in promotional months, and the IRC Section 280F luxury-auto cap that strands meaningful basis on business-use luxury purchases. This guide walks through the mechanics of why luxury leasing dominates, the MSDs option for further money-factor reduction at BMW and Audi, the Section 280F limitations on business buyers, and the specific scenarios where buying a luxury car (typically CPO at year 3) still makes sense.

The steep year 1 to 3 depreciation case

The Mercedes-Benz S-Class lost roughly 40 percent of MSRP over its first 3 years per the Kelley Blue Book industry depreciation tables. A $115,000 S-Class is worth roughly $69,000 at year 3. A buyer who paid cash for the vehicle has experienced $46,000 in unrecovered depreciation. A buyer with a 60-month loan at 6.89 percent APR has paid $52,000 in principal and $19,500 in interest through month 36, holding a vehicle worth $69,000 with a $63,000 loan balance: $6,000 of equity and $19,500 of interest sunk.

A lessee on a 36-month lease with the same vehicle at a 0.00125 subvented money factor and a 60 percent residual ($69,000) paid roughly $24,000 in lease payments plus $2,000 in fees, and walks away at month 36. The lessee's out-of-pocket cost was $26,000 versus the buyer's net position of $46,000 in depreciation. The lessee paid for the depreciation portion they actually used; the buyer also paid for the depreciation portion they actually used but also locked up capital and is on the hook for the residual.

This math is specific to the high-depreciation luxury segment. On a 3-year hold of a Mercedes E-Class (which depreciates more gently), the gap narrows. On a 3-year hold of a Lexus LS (which depreciates somewhere between European and Japanese luxury norms), the gap narrows further. On an S-Class, 7 Series, A8, or comparable flagship, the lease almost always saves money over a 3-year horizon for personal-use buyers.

Section 280F luxury auto limits for business buyers

IRC Section 280F caps the first-year depreciation deduction on passenger vehicles used for business at approximately $12,200 for 2026, plus the prevailing Section 168(k) bonus depreciation percentage applied to the remainder. Year-two cap is around $19,500, year-three around $11,700, year-four-and-beyond around $7,000 per year. A business buyer of a $115,000 Mercedes S-Class can only depreciate roughly $12,200 in year one, $19,500 in year two, $11,700 in year three, and $7,000 per year from year four onward.

Over six years, total depreciation deduction caps at approximately $74,800. The remaining $40,200 of basis is stranded; the buyer recovers it only if they sell the vehicle and have a gain or loss adjustment. For a high-bracket business buyer (37 percent federal marginal rate), the stranded basis represents $14,900 of foregone tax savings. The lease path, by contrast, allows the business to deduct the full lease payment in proportion to business use percentage in the year paid, with no luxury-auto cap (a small inclusion amount adjustment applies for leased vehicles above the FMV threshold but the cap is far less restrictive than the purchase-side 280F limit).

For business buyers of vehicles above $80,000 MSRP, the Section 280F constraint is meaningful enough to flip the buy-versus-lease decision on tax considerations alone. Talk to a CPA before signing.

Multiple security deposits at BMW and Audi

BMW Financial Services and Audi Financial Services allow lessees to make multiple security deposits at lease signing to reduce the contract money factor. Each MSD equals one monthly payment, held by the captive throughout the lease and refunded at lease-end. Each MSD typically reduces the money factor by 0.00007, equivalent to about 0.17 percent APR. BMW allows up to 7 MSDs; Audi up to 10.

Concrete example: BMW X5 lease at $1,150 per month base, money factor 0.00200 (4.8 percent APR equivalent). Without MSDs, total payments over 36 months: $41,400. With 7 MSDs ($8,050 held by captive), money factor drops to 0.00151 (3.6 percent APR equivalent), monthly payment drops to approximately $1,068, total payments over 36 months: $38,448. Savings: $2,952. Subtract the opportunity cost of $8,050 held by captive for 3 years at a 4.5 percent alternative yield = $1,134. Net MSD benefit: $1,818 over the 36-month lease.

MSDs are most valuable when the alternative use of cash is low-yield (checking account, short-term Treasury at sub-5 percent) and when the lease term is long enough to amortize the benefit. For lessees with high-yield alternative uses (paying down high-interest credit card debt, investing in a tax-advantaged retirement account with employer match), the MSD path is less attractive. Mercedes-Benz Financial Services discontinued their MSD program for most contracts after 2023, though some dealers can still arrange similar structures on request.

Worked example: 2026 BMW 750i

MSRP $112,000, negotiated price $108,000. Personal-use buyer with super-prime credit.

Lease: 36 months, 12,000 mi/yr, subvented money factor 0.00125 (3.0 percent APR equivalent during a promotional month), residual 56 percent of MSRP = $62,720. Monthly base payment $1,485. With 6.5 percent state sales tax: $1,582. Acquisition fee $925. Total 35 additional monthly payments of $1,582 = $55,370. Add disposition fee $475, walk away at month 36. Total lease spend: $58,000 with $0 asset.

Buy: 60 months at 6.89 percent APR, $20,000 down, financed $88,000. Monthly payment $1,737. Total 60 payments $104,220. Plus down payment $20,000. Total spend $124,220. Vehicle at month 60 with 60,000 miles, market value roughly $40,000 (36 percent of original MSRP, typical for full-size German luxury at year 5). Net 5-year cost: $84,220. OBBBA loan-interest deduction does not apply (BMW 750i is German-assembled). Net 5-year cost remains $84,220.

At month 36, lease spend $58,000 versus buy spend at month 36 ($20,000 down + 36 payments of $1,737 = $82,532 spent, vehicle worth roughly $58,000, loan balance roughly $40,400, equity $17,600, net cost $64,932). Buy is roughly $7,000 worse at month 36. On a 5-year hold, buy is $26,000 worse than two consecutive 36-month leases ($58,000 times 1.67 = $96,860 in lease payments, $0 asset, net $96,860 versus buy net $84,220, so actually buy wins by $12,640 on 5-year). The 36-month picture strongly favors lease; the 5-year picture is closer; the lease wins on liquidity preservation and downside protection if the vehicle depreciates harder than residual implies.

LUXURY: LEASE WINS FOR 36-MONTH HORIZON

For 3-year hold, personal-use luxury car buyers, leasing wins on cash flow, residual-risk protection, and access to subvented promotional rates. For business buyers of $80,000+ luxury vehicles, leasing wins additionally on Section 280F luxury-auto cap avoidance. The CPO purchase at year 3 wins for buyers willing to hold 5 to 8 years and absorb out-of-warranty repair costs from year 6 onward.

MSDs at BMW and Audi provide additional money-factor reduction worth $1,500 to $3,000 over a 36-month lease for lessees with low-yield alternative uses of cash.

Luxury car FAQ

Why is leasing more popular for luxury cars? ⌄
Three reasons. First, luxury cars depreciate steeply in years 1 to 3 (typical S-Class loses 35 to 45 percent of MSRP in 36 months), creating high residual risk for buyers. Second, captive finance arms (Mercedes-Benz Financial, BMW Financial Services, Audi Financial, Lexus Financial, Genesis Finance) subvent luxury leases aggressively to drive brand loyalty and conquest the segment. Third, luxury buyers often prefer to upgrade every 3 years to access new technology and design, making the natural lease cycle a fit. Edmunds market data shows luxury car lease penetration around 50 to 55 percent versus 22 to 28 percent for mainstream brands.
What is the Section 280F luxury auto limit? ⌄
Section 280F caps the first-year depreciation deduction on 'luxury autos' (a tax category that includes essentially all passenger cars, not just luxury brands) used for business. For 2026, the first-year cap is approximately $12,200 plus the year's bonus depreciation percentage applied to the remainder, per IRS Rev. Proc. annually updated. Year-two cap is around $19,500, year-three around $11,700, year-four-and-beyond around $7,000. The practical effect: a business buyer of a $90,000 Mercedes S-Class can only expense roughly $12,200 in year one and $50,400 total over six years, with the remaining $39,600 of basis stranded. Leasing avoids this cap because the lease payments are deductible as ordinary expense.
What are MSDs (multiple security deposits)? ⌄
BMW Financial Services, Audi Financial Services, and historically Mercedes-Benz Financial Services allow lessees to make multiple security deposits at lease signing to reduce the money factor. Each MSD typically reduces the money factor by 0.00007, and up to 7 to 10 MSDs are allowed depending on the captive. Each MSD equals one monthly payment, held by the captive throughout the lease and refunded at lease-end. The math: 7 MSDs at $850 per payment = $5,950 held by captive, money factor reduced by 0.00049, equivalent to an APR reduction of 1.17 percent. On a 36-month lease, savings are roughly $850 to $1,100. The capital cost: lost yield on the $5,950 held by the captive. At a 4 percent alternative yield, three years of opportunity cost is $714, so net MSD benefit is roughly $150 to $400. MSDs are most valuable when the alternative use of cash is low-yield.
Why do luxury cars depreciate faster than mainstream cars? ⌄
Several mechanisms. First, mainstream-brand buyers often value reliability and resale; luxury buyers value newness and brand status, creating a smaller pool of used-luxury demand. Second, luxury vehicles incur expensive out-of-warranty maintenance (control arms, infotainment, air suspension) that scares off used buyers in years 5 to 7, depressing year 5 residuals. Third, captive lease subvention floods the used market with off-lease luxury inventory after 36 months, suppressing prices. Fourth, technology obsolescence (driver-assistance, infotainment) hits luxury vehicles harder because the differentiation versus newer models is more visible. The Manheim Market Report tracks these patterns quarterly and the luxury-versus-mainstream depreciation gap has widened modestly since 2020.
Is buying a CPO luxury car a smarter path? ⌄
Often yes for buyers willing to hold 5 to 8 years. A 3-year-old CPO Mercedes S-Class costs roughly 50 to 55 percent of original MSRP and includes manufacturer-backed extended warranty to 6 years/100,000 mi from original sale. The depreciation curve from year 3 to year 7 is gentler than year 0 to year 3, so the second owner takes a smaller percentage hit. The risks: out-of-warranty repair costs in years 7 and 8 can be substantial (air suspension overhaul, electronic module failures); used-luxury insurance premiums are sometimes higher than mainstream equivalents. The CPO path makes more sense for buyers who can absorb $1,500 to $3,500 annual repair contingency from year 6 onward.
How aggressive is luxury lease subvention? ⌄
Highly seasonal and model-specific. Mercedes-Benz, BMW, Audi, and Lexus typically run their most aggressive monthly lease offers in December (end-of-year sales targets), March-April (model-year transitions), and August-September (next-year-model arrival). Subvented money factors during these months can drop to 0.00050 to 0.00100 (1.2 to 2.4 percent APR equivalent), versus 0.00150 to 0.00250 in non-subvented months. Residuals are also sometimes boosted during these promotions to enable lower payments. Leasehackr and Edmunds Lease Deals track these monthly. A buyer with timing flexibility can save $1,500 to $4,000 over the lease term by signing during a subvented month versus a non-subvented one.
