If you feel like you got ripped off, you did.
If you dont feel like you got ripped off, you didnt.
Not to sound smart ass-y, but thats really what it comes down to.
Your time frame, your location, what you want, what is available at the time etc etc ...all factor in.
These cars sold for $5k when brand new. LOL
I paid $9500 for my 72 318 fish 2.5 yrs ago...all it had was fresh paint/body and new tires/rims.
A non matching 318 came with it, no idea if it ran or not...seller said it did....looked ok. No exhaust, rad, battery or battery tray, tranny or shaft, no underhood wiring, interior was complete but all apart and needed redone.
It was worth it to me.......I wanted a project car with decent paint but solid in general.
I have a lot into the car at this point too.....little at a time....
Is it "worth" what I have into it at this point? Dunno.
Don't really care. I didnt buy the car as a financial investment.
Its my first real Mopar and I am in love.
There is no way to put a real market value on these IMHO. SUre, the insurance company will...and lord knows the BJ/Mecum auctions have owners thinking they can get big $$$$ for their "one of a kind"....but in reality, our cars are worth whatever we can get for them when we sell them. In your case, the selller got $15k. So its worth $15k.
FWIW, the pics of the car are awesome. Real nice ride IMHO.
Hope your love affair with this red vixen is a long healthy one!
