This is totally legit: Mercedes-Benz : 300-Series 4 dr in Mercedes-Benz | eBay Motors

Looks to be a Euro 300D with a nice blue cloth interior (my favorite blue interior), 4 speed manual, and has a decent repaint. No telling what condition the engine is in but the rest of the car looks nice. I am not sure of the values of those cars but if it is a decent price, it just needs to have those hideous rims replaced with stock rims and the trunk badge and emblem replaced. Might be hard to deal with the seller though, since he is obviously lying about the MPG.
