1975 Dodge Dart Swinger

This has me bewildered. I posted this ad several weeks ago. It's had only 163 views and NO replies. Swingers must not be in demand. Either I am asking too much or it has no retail value. I sold an '86 Monte Carlo LS (that's a V6 FI) last year for $7000.00 and people were almost fighting over it. I have turned down offers for my '55 Chevy for over $8000.00 for the body only. This Dart is in excellent condition, it's loaded with features, everything works perfectly except for the heater core, and it drives like a dream. I certainly am grateful this car didn't go thru the Barrett-Jackson auction. No reserve there so I would have really lost money. Maybe I need to put a 340 or Hemi in it. Looks like Mopar people buy an engine... not the car. Falcons and Corvairs are bringing much more than this Dart. I don't understand. Someone is missing out on a very nice old Dart.
