That seems a little risky, might be kinda beat up despite the appearance. That guy also seems pretty dumb due to his lack of spelling skills and poor grammer use. WOW...
And he just comes right out and says "the engine is in good condition". Oh really, and how do we know that? He didnt mention a tune-up or compression test. I don't like dealing with people that seem like they haven't graduated from middle school... I'd say no go cuz the previous owner probably beat the shit out of it and I don't trust the seller to be honest, but it's up to you.
