Anyone concerns with the car before I make an offer?

Selling an old muscle car on Kijiji or another similar site is hell on earth. Just spent two years selling a 73 Challenger and 71 Dart because of guys just like the one above. They pull you along to the point where you have to store the car for winter and wait another 5 months till you can pull it out again.

I've also got signs on the car itself and trying to drive it around as much as possible to hopefully real someone in that way.
