White letter tires don't look right to my eye either but someone who did not live thru that era may not even notice. Site says only 3 people have looked at it in the past 24 hours so it is not setting the world on fire.
I do like the looks of this one, it's well optioned, and the seats are perfect for a car like this - gotta love that cushy living room couch. The 307 is a bit underwhelming for modern drivers who can't remember what a late '70s or early '80s car drives like and the 200-4R transmission is an early one, so if it's never been serviced or replaced it's going to be a timebomb if you don't baby it. The price is kind of outlandish, I can't see these ever bringing big bucks as a collector item unless it's showroom new.
