Mileage caps and steep per-mile overage
Leases set an annual mileage limit, and every mile over it is billed at the end, often at a fixed rate per mile. Drive more than you expected and the overage can run into thousands. A low monthly payment paired with a tight mileage cap is a common way to make a deal look cheaper than it is.
Ask for: Ask for a mileage limit that matches how you actually drive, and price extra miles up front, since they are cheaper bought in advance than as an overage.
Vague 'excess wear and tear' standards
You are responsible for damage beyond normal use, but 'normal' is often left undefined. Scuffed wheels, small dents, worn tyres, and interior marks can all be billed at return, sometimes at the leasing company's own inflated rates. The vaguer the standard, the more room there is to charge you.
Ask for: Ask for a written wear-and-tear guide with clear limits, and consider a wear protection add-on if you drive hard.
Harsh early-termination penalties
Ending a lease early is one of the most expensive things you can do. You can owe the remaining payments, an early-termination fee, and the gap between the car's value and what you still owe, all at once. Know this number before you sign, not when your circumstances change.
Ask for: Ask exactly what early termination would cost at several points in the term, and whether the lease can be transferred to someone else instead.
Fees buried in the signing paperwork
Watch for an acquisition fee at the start, a disposition fee at the end, documentation fees, and dealer add-ons bundled into the capitalized cost. Each one raises the real price without touching the headline monthly figure.
Ask for: Ask for an itemized breakdown of every fee and the full capitalized cost, and negotiate the disposition fee to be waived if you lease or buy again.
Gap between the car's value and what you owe
If the car is written off or stolen, insurance pays its market value, which can be less than your remaining lease balance. Without gap coverage you owe the difference out of pocket. Some leases include it, many do not, and dealers often upsell it at a markup.
Ask for: Ask whether gap coverage is included, and if not, compare the dealer's price against adding it through your own insurer.
The residual value and buyout terms
The residual is the car's assumed value at lease end and it sets your buyout price. A residual set too low inflates your monthly payment; a buyout price locked far above the car's real worth makes keeping the car a bad deal. This number quietly shapes the whole lease.
Ask for: Ask for the residual value and the exact buyout price in writing, and compare the buyout to the car's likely market value before you commit.
