How much would you spend on it?

There are just a few things to consider when buying a classic.

What is it worth to YOU?

What is it worth to anyone else. This only comes into play if maybe someone else will buy it and its gone and you wanted it. Or if you bought it and later want to sell it.

Can you do the work to make it what you want or afford to pay it done/
I think its changing though yeah 20 -30 years ago c bodies weren't wanted but now?... I work with a guy who occasionally drives his 68 Polara in and its a 383 car a huge boat to me but he loves it. it isn't junk either some of these big cars were taken care of garage kept etc. The mindset that "its a c body part it out..." may want to rethink it especially if the car is savable.
