Stain on parchment seats.
 

I am looking at a 2019 CX-5 GT w premium package (ventilate seats, elec folding mirrors, heated steering wheel & back seats) 53K miles for 20K
Two questions

1) Is this a fair price?

2) The seats are parchment and have a couple stains. They said their color guy can fix the seats to cover stains / look new again. Does anybody know what the color guy does? Like do they dye or paint them and is this a good idea?
The vehicle is in good shape mechanic wise, 1 owner, clean car fax W regular oil changes & maintenance.

They should be able to clean/refurbish the seats, but keep in mind it will likely happen again. I always get black leather for that very reason.

As for the price, have you looked at the online sites for a suggested price (KBB, Edmunds, etc)? Also, what are other places you have looked asking for similar cars?
