That purple convert is a real 340 car but it's tough...ie rotten unibody.The person that purchased it last year was a GM guy who had always lusted after E Bodys but knew nothing about the rust issues that are common to them in these parts.That car also had a AAR dash tag on it....not sure if thats been corrected or not.I believe that car needs heavy reconstruction much like the purple shaker 71 that Keith Sims just did the unibody on.Might as well buy a better car which is what the current owner is hopeing to do...flip the rotten lump and upgrade.
