A good friend of mine sold his 58 300 vert about 6 years ago and it was a MAJOR project car .
I dont remember the exact amount but I think he got right around $10- 15k for it. But it was a black car and with everything to hang factory air on it. Which best I remember is the main reason the buyer wanted it . AC on these cars were pretty rare.

IMO $75K on this one is a tad high. But running and driving car are huge plus. That said I think something in the 50-60k range would move it . But I would REALLY want to see this one in person before pulling the trigger

Done nice they are 6 figure cars
