Hi Gaz,thanks for the welcome you will have to bear with me because Im new the Forum thing and Techno Stuff anyway a bit of History,Im 69 have owned my BMW Z3 Roadster for about a year its a 2001 2.2 done about 42000 miles,I think its a cracking car and really enjoy the way it drives and behaves,although originally I was a bit cautious about getting to invoved with repairs ect,after reading some of the aticles on your site I feel a little more enabled,IDo have an engineering background,I was an apprenticed motor mechanic and worked as a motor vehical engineer for the local Police Force but I left the Trade in 1998 due to family commitments and had a career change to work in the Lift Industry.Anyway brilliant site and very interesting and informative
