1998 328i 330,000km
Original clutch and it's still fine (knock on wood dammit!)
Last 5 years have been track only. That clutch amazes me!
Engine untouched other than MarkD mapping and intake
Religious oil changes, plugs every few years
Original tranny, fluid changed once or twice
Lost count of used diffs and ratios (about 4 or 5)
I put in my own oil pan baffles, did an oil pump while I was in there
Secondary air pump flakes off every now and then. I'd remove it but I'm to lazy to get it programmed out.
