Is it possible to trade out of my lease or too flipped?

Seriously depends on why it’s rare. If it’s rare because the car sucks, then why would someone pay a premium for it used?

If it’s rare because it has a race heritage and the manufacturer only made 200 of them, then it would probably depreciate slower and in some cases retain most of its value or even appreciate. (2005 Ford GT)

Rare doesn’t mean good or desirable, you could lower your payment to zero if you found a snowy off ramp
