Had a great day driving the z3 on backroads, no traffic, sunny day with the top down. Next day, turn the key...nothing. No click, no slow turning over, nothing. Battery read 12 volts, tried to jump it, nothing. I'm guessing it's the starter or the starter solenoid. My question is, why did the make it so difficult to get to the darn thing? Looked it up on the internet, and it seems like you have to diassemble half the engine to get to it. Since nobody in this town will work on bmws, I'm afraid I'm going to have to get real familiar with working on it myself...
