I am apparently new on this forum, but I am definitely not new to Z3s. If you are browsing this forum looking for Z3 information, then you won't find very much. However there is a mass of information on the web for the Z cars, and I doubt there is a problem that exists that there isn't a well documented solution for. http://forums.bimmerforums.com/forum/forumdisplay.php?f=137 http://www.bimmerfest.com/forums/forumdisplay.php?f=7 The Z3 is the last of the great User Friendly BMWs. In the vein of the E30 and older BMWs, the Z3 lacks all the convoluted computerized problems of the current crop of late model BMWs. There isn't a system on the Z3 that a competent shade tree mechanic can not fix on their own. There are a few common problems, but nothing that is so complicated that it would be overwhelming to undertake on your own other than the sub-frame and bearing failure which Randy can take care of pretty easily. http://www.spcarsplus.com/ And even these are very isolated issues that probably won't affect your car. The body panels un-bolt from the car (roof stays on the coupes) so you can do anything you want to the panels while they are removed from the car. The rear windows are replaceable. The AC controls are manual dials that will not short out. The differential can be swapped out with lots of options. You can swap in various transmissions if you don't like the one it comes with. The seat adjustment motors are simple and are easily diagnosed. The Stereo is basic and well laid out in design and its not tied to 5 other systems so it takes them all down when it breaks. I have personally repaired or upgraded every system and part in the Z3 over the years. Its all been rather simple, if sometimes a bit tedious. I highly recommend them to everyone and anyone interested in a car that is an instant classic that is owner serviceable. They made about 300,000 Z3s. To contrast that to other BMWs, they made 180,000 E36 328i, and 256,000 325i cars of the E36. So these cars are not super rare, parts will always be around, and they will always be easy to fix. Feel confident in your Z3 purchase, and do a little research. The bad advice is rampant on the Z3 from people who know nothing about the Z3. Due to its simplicity, its the easiest modern BMW to own, without a doubt.
