I'm looking for some advise. I want to know if it would be a better to buy a 67 RS or a 68 convertable (not RS or SS)? Both cars have matching 327's and are in good condition. The 67 is all original, the 68 has been restored. Both cars have less than 90k miles on them. I like both cars so there isn't one I like more than the other. Any advise would be greatly appreciated.

What do you want. ? Rag top or not. RS SS is more of the hot rod.
Both rag top and RS SS are premium over a stock coupe.

there is nothing like a rag top, but you will have to replace the top every few years. But they seem to hold there value a little more. try to test drive them both to see what you want.

rag top worth more money in the long run

If the RS is an extra clean survivor then it could be worth more than the vert. Remember to check it over well though cause it is a 40yr old car and could just be a old restoration (i've run in to it a few times).

p.s. i own a 68 vert.
