Been lurking for a while, but since I've just posted my first comment I thought I'd better do the 'intro' thing as well.
I've had this UK import Z4 since 2013 and have had a lot of fun with it, along with a few jobs that needed doing (soft top motor sitting in a pool of water - most common fault on these cars). I've done all of the jobs myself so far including the oil changes, new discs/pads, replacement roof motor (can almost take roof off blindfolded now...), brake fluid, ABS pump replacement and so on. Also using NCS and Carly to do coding. It's been a great learning experience, and fun to drive (that's the point after all, isn't it?)
And since I've been around long enough to know these threads are useless without pics...
