Thanks for the pointers. I've tried a couple of BMW forums, but much to my dismay they are mainly non-technical talk about 3-Series cars. Kudos to this site and the members and moderators that make it what it is. I'm trying to start a technical revolution at some of the BMW E39 sites, but I plan to come here for reliable technical information for the foreseeable future.
There really is a great group of technically astute car nuts over here.
I really wish that the 1997 E420 Sportline that I test drove back to back with the 1998 BMW 540i Sport was comparable, but I couldn't believe the difference in two cars that are supposed to be closely matched. The support at MercedesShop was the main reason that I was looking at Mercedes over BMW to begin with…
1998 BMW 540i Sport
1989 BMW M3
1979 Triumph TR7 (1st car)
1986 BMW 735i (Sold)
1980 BMW 320i (Sold)
