I liked my '65 GTO, or '66 which I think looked great. Another nice ride is the 64 Chevy Impala.
As for me and Grandma we like our TR6 and it is great fun having the grandkids lined up in the front lawn waiting for their turn to ride. The neighbors get to see a lot of really big smiles!
As for selling, you might wait for spring, March, April, May, to get a better price.
