I currently own a well restored 75 2002 and am looking at gettting a 3.0 CS or a 635 CSi in addition. Having not owned or really driven either of these much, can anyone share their thoughts about the pros and cons of each (e.g. driving experience, cost of ownership, availability of parts and skilled mechanics). At this point I'm leaning towards the 3.0 CS and considering an automatic (I know, a stick is probably the only real enthusiast choice, but traffic here in Atlanta is the pits).
