I Fell Into MOPAR

Welcome to the site, I love the cars and the old jeep is just too cool!
Although it's easy to have over 70 grand in a car build, that's not always what they are worth when selling.
A lot of it depends on the year, originality, overall condition, and modifications.
For example, if the Super Bird was 70 grand, it would be a steal.
If the '71 Cuda was 70 grand, it would be a good deal.
But the '72 Cuda for 70 grand is over priced by a lot.
Maybe the '72 Cuda for 50 grand would be top dollar if it is extremely nice.
Would you be able to resell it for that much?
Probably not.
Would you be able to build it for 50 grand?
Again, probably not.

If you plan on keeping the car and enjoying it for many years, and you think the price is fair, then go ahead and pay the 70 grand for it and don't look back.

It's your money, so spend it as you see fit.

This is my opinion FWIW...
