The way I looked at my end of lease, what do used FFE's cost? Can I buy a used one for less than what they want to buy out my lease. In my case, the answer was oh heck yeah there were a lot of used cars for a lot less than my lease buy out. So that's what I did, turned in the lease and bought a used FFE.
The only thing to remember about a used car, you'll have to pay sales tax, transfer fees for the plates, title transfer, and possibly a Doc fee at the place you buy the car. And you might have to buy tires.
Your lease end may be $9,200 all in, no other fees. And you might get about another 10,000 miles on those tires - maybe maybe not. You know the tread depth.
Only you can answer the question about what used FFE's cost in your area - or an easy tow away within 200 miles.
The other positive with a used one - you might trade up and get a California car that is in better shape than what you have now. If you live anywhere other than a sunshine state, your car has rust on it already. And it rattles more than a California car - you've driven over a lot more pot holes than they do.
