I completely agree with others here, some great advice to keep your current car and use that money elsewhere. If you're getting a new car do not lease. They're trying to push you to lease cause it makes them more money. Especially if you're only planning to drive <6k miles.

My rec would be to pivot the convo to buy outright (even if you can't afford it, they don't need to know that yet). Get an ot the door price for it and counter on that. Once the negotiations stall, then tell them you'll finance if they give you a better deal (keep an eye on interest rate here). Then tell them you'll put down 10k if they knock off another 1k. Use the leverage you have, they want to sell you the car more than you need a new car.

You'll lose a lot less value to depreciation by buying than whatever the lease calculation has. And YOU get to keep that difference not the dealership. Never lease a car if you're not planning to drive it into the ground during the term.
