those are nice! I hate to say this, but the only problems I have really had with my e36 has been an oil leak and now my power steering, I will be fixing, and/or getting both fixed soon. Recently when I thought it was my alternator being the problem, it turns out when I got new swaybar mounts welded on, the alternator ground wasn't put back, I didn't check that arrggh! Until a few days after I bought a new alternator and was about to put it in, I guess it is some preventative maintenance. I have gone on other forums and peoples coolant expansion tanks have exploded?
Maybe it's a manual e36 thing? I mean I do go all out on my car sometimes, driving wise.
