Jarret,
If this car still had the 3-point star on the hood one would say "it's a lot of miles but these things (Mercedes Benz) go forever. The maintenance is however high end but as Doc said "it's all on this forum". For such a high tech car it is actually fun to work on if you take your time, go step by step and most of all get ahold of a Crossfire shop manual on CD. All the info in here on this forum but I like the CD just seems easier for me when I need to look up something.
All in all I love this car, I had a 2004 originally and loved it ithout any troubles. I have also owned Audis and niether are cheap to service so if it's between these two cars... Welcome to the forum!
