Questions about used G63

Hello. I've been looking to purchase a G63 for the past few months. I finally found one that seems like it's the right choice for me. It's a 2013, 115K miles ($56k). Is there anything I should particularly be worried about when owning this vehicle? I have owned Mercedes vehicles in the past and like working on my own cars and know how to change oil, brakes, etc. And, another thing I was curious and a bit worried about, do these cars get lots of attention on the road? I don't mind some attention and looks I just don't want it to be too much.
