The Model Black lets you add multiple security deposits to a lease it prices, where that car's captive lender offers them, because they are the one lease lever that lowers the rate without spending the money.
An MSD is a refundable deposit, roughly one month's payment, that the lender holds for the term. Each deposit buys a small reduction in the money factor; the size of the reduction and the cap are set by the captive lender (with Mercedes-Benz Financial Services, for example, each one lowers it by 0.00007, up to 10 deposits, as reported by lessees on Leasehackr and MBWorld in 2025 and 2026).
| Money down | One-pay | Multiple security deposits | |
|---|---|---|---|
| What it does | Reduces the amount financed | Prepays every payment, lender cuts the rate | Lender cuts the rate, money held as a deposit |
| Refundable | No | No | Yes, at lease end |
| Risk in a total loss | Down payment is gone | Depends on contract | Deposits are returned |
| Best for | Lowering a payment when cash will not be missed | The cash buyer who keeps cars 2 to 3 years | Anyone with idle cash who wants the rate cut and the money back |
Every vehicle page whose captive lender offers MSDs has an MSD control beside the term and mileage selectors (0 up to that lender's cap, which is 10 with Mercedes-Benz Financial Services). Change it and the monthly payment, the drive-off total, and the deposit amount update together. The dealer's selling price does not change; only the lender's rate does.
Availability varies by lender and state: some captives offer MSDs (Mercedes-Benz Financial Services does in Arizona and Nevada as of September 2026), some have discontinued them, and the vehicle page shows the option only where that car's lender allows it. The dealer confirms at contract.
It depends on the captive lender: Mercedes-Benz Financial Services allows up to 10, others cap it lower or do not offer MSDs at all, and the vehicle page shows the cap for that car's lender. The Model Black prices 0, 3, 5, 7, or 10.
No. Money down is spent; deposits are held and returned. That is why The Model Black's lease examples show money down separately from MSDs.
Usually not; lenders treat them as alternative rate reductions. Compare both on the vehicle page and take the one that fits.
They are refunded or applied toward the purchase, per the contract. Ask the dealership to confirm its process before you sign.
