I need your honest opinion

Hi there. First question I have is how much could you sell it for.
I honestly have no idea. There are now two '75 Valiants for sale, a Brougham and a Scamp. Both in excellent condition, both with a V8 (318 and 340 I guess), both for around 30 grands.
There's a '67, 170 Slant Six car, also good condition for 15.5 grands. Another '68, in excellent condition, also with the 170, is for sale for 25 grands.
There are 3 early 60s Valiants for sale, all in good coindition, all for around 16,5-20k

In total, I have paid 15k for mine, so 15k would be amazing, but I think 10-12k is realistic, or even lower.
