Another (yellow) 4 door 510 for sale in BC. I had a chance to look at this one and other than the obvious body issues it seems to be pretty good - clean start, runs ok, no smoke, rides ok. Just noisy so probably needs tuning or there is an exhaust issue. Interior seems pretty good also. I did not get it up on a lift so could be worth doing.
The seller is very open and transparent about the issues. I believe he has parts for sale also (engine etc).

Others can probably comment on likely body costs. I would probably change the seats too. Just a bit too much project for me...
