Might buy a 65 Dart

Sounds like that car has a lot that needs to be taken care of before it can be driven.
Plus a four door is tough car to sell if you need to resell it.
I know it cost more but this might be a better one to consider and its a drop top too with rebuilt engine & trans with new tires http://nashville.craigslist.org/cto/5155364741.html
My guess it is would be cheaper when all the time, work & aggravation is taken into account.
