Back to the OP, why are you looking to lease a car ? Can you not finance the car Q50 that you want ? then at the end of the term you either own the car that you want or trade it in and finance a newer one and lower your monthly payments.

I live in Canada and I don't pay to much attention to what finance vs lease rates are in the US, but up here they are about the same if not more to lease, the only thing is you need a bit more of a down payment for the finance but you own the car at the end.
