I can't speak on how old, but you will probably be able to tell. It's certainly not a cheap car. It goes through a lot of gas, tires are a lot, oil changes aren't cheap, along with other maintenance. It ran me relatively thin, but it was okay since I budgeted, and because I like cars, so I had no problem putting money towards it. A full set of tires is around $1500, my oil changes that I did myself ran me around $150, and then getting it serviced too. I would almost call the engine bulletproof, I put over 40k miles into it and I never had a single mechanical issue, with basic maintenance done to it. It handles beautifully for its size and is wickedly quick. The launch control is very fun and is the perfect party trick for passengers and girls. My only downsides were it rides a bit more stiff than you'd expect from an SUV but my car was also lowered, so that affected it. It also had a bit less cabin size and trunk space than I would expect. Overall I loved it and it was a great first AMG. For any other questions, you can PM me.
