CL find... 68 GTS

I went and checked out the green GTS today. It's a real mess, I'm pretty positive that it is not the original motor or trans. Motor is wrong color with blue factory paint not red, also has later model exhaust manifolds. Transmission bell housing is windowed in the 12 o'clock position not sure how that could of happened but not good. Inner fender is rusted out where the battery mounts with a steel plate tack welded in it's place. Need anymore information let me know, price is $5,500.00 I didn't even bother making an offer.
Im gonna let the cat out of the bag, I did too Saturday. I even brought a trailer , I just couldn't stand to look at it!!! I swear a 500 lb homeless person must of lived in the front seat, actually is so smashed I don't think it could be fixed, their was a 1ft by 1ft hole in the fender apron where the battery goes , the hood has a big buckle in ithe front, its got homemade wiring, solinoids off fords and motorhomes and who knows what else mounted to the fender liners, it had a blowout on the drivers rear that bent the trunk floor up 3 inches. I could go on and on and on. I offered a gracious $3500 (at my better judgement) in which he refused. He is down to $3750 but??? I degress........
