At 86k miles on my 1998 BMW Z3, the thin sheet metal bracket holding the rear differential up in place welded to the chassis split in half causing the rear end to hang. This is the second time it has happened, also at 93,500 miles, just 8 months later. The clutch is still original and the car has never been abused, or raced. I always baby the car because gas is so expensive, and this seems to be a problem with alot of other Z3's that I have seen online. This is clearly a manufacturing flaw. BMW claims the car must have had some rear end impact, even though this is clearly not the case. I would like to see them replace this part with thicker, or stronger metal as it can be a very serious problem if the differential falls out at high speeds.
