What can you get for $2500?
Honestly - as much as I love my Dart, and I love Mopars.. $2500 will get you "in the door" with something that either needs a fair amount of work, or will be very basic... and from there, expect to spend some decent money to get it where you want it. I bought my wife a '66 Mustang a year ago or so, and I was able to completely re-do the interior (new dash pad, seat covers, carpet, door panels, added headrests, all new interior chrome trim, .. all for about $500. There is virtually NO aftermarket support for Mopars.. there is a TON for Chevy/Ford. an example - expect to spend $250 for a pair of door panels for a Dart.. you can get a pair of new door panels for a '66 Mustang for $60 .. that's just one of many examples.
Again - I'm not trying to disrespect Mopar.. I love our cars.. but if you're on a budget - Mopar is NOT the way to go.
