'93 BMW 740i (60 miles/day, 186,000 miles). Wife drives an '89 260E (W124) with 150,000. SL only when the weather's right. Although, did decide to take it out last Sunday since it had been in garage so long. Top was still down, so I put it up...unfortunately, didn't even think about the temp outside as I usually have the hardtop on this time of year. I was painfully reminded that the rear window is plastic as I heard it crack. Bad mistake--$$$$
