Update, I want ahead and pulled the trigger and bought 2005 Crossfire,yellow. This is an outstanding vehicle, strong running and handling. I'm very very pleased with my purchase. I'd like to extend a big thank to everyone who expressed positive comments and helpful insight in making my decision. I will say, I was always interested in this vehicle due to the fact I have one Mercedes already. I would like to verify with members if I could in that I'm takeout the advice of members on the website and carry an extra CPS sensor. I priced them AutoZone, $114 a no-name. AutohausAz has one for $43. If you could please verify for me the AutohausAz CPS is for an 2005 SLK 320, part number 003153282. Also there is some confusion of what type of tool needed to replace this item. I believe it's some type of star reach? Thank you again and as I learn more of this vehicle I will be more than happy to engage in conversation with anything I find from my perspective and always appreciate your viewpoint and knowledge, thank you
