Whoever is selling it never graduated high school from the looks of the description. The car looks like it's pretty sound. But they never show you the trunk or the lower quarters among other things. I'd be pretty cautious on it myself.
I doubt it's a scam. He has a phone number and made offers to come view the car. Prob. not a bad deal if its solid...looks like someone is turning it over though, seeing as how he didn't even get the engine correct in description.
