I bought a 2009 Mercedes 350 4matic with 163k miles. The Carguru sales said it passed the 160k mile check-up and the only thing wrong with it was the left wheel bearing needed replacement. I had the work done the first week I owned the car. Within the first month I had failure of the drive shaft which impacted the steering rack, a failed rear differential, rear wheel tires different size, failed interior roof console, and today, having it towed due to engine light coming on with the engine misfire. I have so far invested over $8k in repairs to a car I purchased for $4500. As-is Before you buy from Cargurus, don't believe anything they tell you. Have the car checked by a qualified mechanic.
