after 30 yrs in this hobby I have found that whenever you go to sell an old mopar, 99% of the potential buyers that come to look will try to nitpic, whin, *****, moan about anything and everything. only the REAL guys will look it over, and IF there is a flaw, will point it out with respect and dignity! I can take someone pointing out a flaw. not the BS!
I have learned to tell them to look it over, ask any questions I will gladly answer, IF they want the car and do not LIKE whatever I did with it, THEY can change it when they get it home! or thanks for looking!
sure you can do things with the car to reduce the numbers of buyers, in my opinion, funky paint jobs, ( costs $$ to change)non original seats, ( some parts of the country parts are hard to find), etc. IMO frame connectors should have come with the car from the FACTORY! if just weld to frame rails easy to cut off and grind welds off. most people now days would welcome enlarged inner wheel housing, UNLESS he is a purist, number crunching, kind of guy.
lets face it, the old car market is more of a buyers market and has been since 2008 or so. our economy is no great. if a car is well a dvertised and doesn't sell in a reasonable length of time, then it is probably overpriced for the market.
A bodies are the bottom of the barrel Mopar wise. the 68-9 cuda is a good model, for an A body, 340 car to boot. but it is worth what someone will pay, just that.
