The Model Black prices every lease at 10,000, 12,000, or 15,000 miles a year so you can see what your real driving costs before you commit.
Excess miles are charged per mile at return at a rate the captive lender sets, typically $0.20 to $0.30 (Mercedes-Benz Financial Services charges $0.25, as published by its dealers in 2026), so 5,000 miles over at $0.25 is $1,250. Miles you buy up front cost less than that, and miles you do not use are not refunded, which makes the choice worth a minute.
| Situation | What happens | Cost |
|---|---|---|
| Drive 2,000 miles a year over a 10,000 allowance for 3 years | 6,000 excess miles at return | $1,500 at $0.25 per mile |
| Buy 12,000 instead | Higher payment for 36 months | Roughly $540 to $1,080 total |
| Drive 2,000 miles a year under a 12,000 allowance | Unused miles | Nothing back; equity at lease end may be slightly higher |
| Buy the car at lease end | Mileage no longer matters | $0 in overage; the residual is the price |
Change the mileage on any vehicle page and the payment updates on the lender's adjusted residual. If you are near the line, price both allowances and note the difference; save the allowance you want in your deal so it is already in the numbers the dealership receives when you send it.
Typically $0.20 to $0.30 per mile over the contract allowance at lease return; Mercedes-Benz Financial Services charges $0.25, as published by its dealers in 2026. Your lease contract states the exact figure, and the vehicle page shows the per-mile charge its estimate uses.
Some lenders allow a mid-lease mileage adjustment; ask the dealer before signing. Buying at signing is the sure route.
No. Over-buying miles is the same as overpaying the payment.
Yes. Higher allowances carry lower residuals, which is where the higher payment comes from.
