How much would you spend on it?

You should not ask me that I AM CHEAP!!!!
My rule of thumb in my old age is NEVER buy any car to put $ and time in that I would not still love IF I wanted to sell it and NO ONE wanted to buy it!!! and I have always been in the mindset of my hobbies should not ever be upside down. Hard to do.
That said, not everyone wants a four door or a big car/
Canutes love C bodies. (But too cheap to pay postage) ha... JOKE!!!!
Hard to buy any complete car for less than $1500 unless a rusted out POS.
Any car that runs and drives has a value. And hard to sell those that don't!''

I have always loved the look of the 65 C body.

I would buy the OPs above mentioned car and just get it running and driving SAFE, and call it good. OK so maybe knock, beat, pull, cut that dent out.
You have to remember I am OLD and still live back in 1990!!!!!!!!!!
I call opening a can of vienna sausages and a box of ritz crackers....eating out!!!! (Moon Pie for desert!):poke::thumbsup:
