1967 Plymouth Barracuda Fastback

It's a really nice car. But just like you've probably noticed with houses, even though they're solid the owners have spent $ on things you don't like and you'll make changes as soon as you get your hands on it.
If you're not getting your price on ebay, that's probably the problem. Everybody wants it for nothing right now so they can flip it (ie:Fast n Loud)
This is a bad time to sell off toys at a good price.
Two pieces of advice if you want.
Keep the car! You love it, you've invested yourself in it and you will kick yourself badley for letting it go one day. The car will only appreciate in value. Believe me I go to the shows in my newer model Nippon POS and wish I had any one of my 3 Mopars back.
Thinktwice about buying any house! It's an anchor which can drown you!
You never really own the property anyway, it's just a lifetime lease at best.
