Finance options for a pricier older car (private sale)

I’m shopping for a C7 Z06. Some of the ones I’m considering could be as old as a 2015 model year. I’m also looking for exemplary examples, so they’re falling in the $80-90k range. Without pulling any actual inquiries, a bunch of sites don’t even list that they finance cars that old, if they do it’s a very short term or very high APRs.

I’m looking for recommendations on the best financing options for this type of situation. Thanks!
