I would be wary of the 62k number, it could be 162k... it could have been some little old lady's go-to-church car, and it just gave it up one day so she got rid of it.... who knows for sure. only the guy who put the 355 in does.
is is worth $9k? *I* wouldn't give 9k for it. Unless it truly is pristine inside, outside, underneath and every place else, optioned out the wazoo, everything works, and it drives straight/like new it just isn't worth that. to me anyway.
more likely story is a dealer sees a 25 year old car that isn't falling apart and thinks he's got a RARE! ONE OF A KIND! (cough) classic or something. You'd be surprised what a little bit of elbow grease, armor all, and wax can do to make a car *look* good on the surface. I'd be skeptical.
But, if you're that interested, have them jack it up, crawl around underneath looking for *any* rust on the body (anywhere on it for that $) and frame (rear rails, up on top of the frame under the doors...), look to see if its been repainted and/or wrecked and repaired, too. Bad repaints are easy to spot, there'll be overspray in places there shouldn't be and likely mask lines and thicker paint around the doors/trunk hood etc. check the body lines for straightness, make sure you see it on a good level bit of concrete....
basically give it a *really* good going over if you're considering it.
