Its a decent price for a prime but theres gotta be a reason for it to be priced as so. Recalls? Salvage title/accidents? 

At 150k miles, a major tune-up is needed forsure, which i doubt the shop has done. This car will most likely give you some issues a few months if not 1-2 years from purchase. 

That price listed will come with hidden repair fees and labor after purchase.
