I've had a few aswell.
900SL MK1, 900SL MK3, 900SL MK5, 2x 851 strada's, 916BP 916SPS, 996SPS, 998R. They all been and gone, still have another 900SL MK1 and the 888SPS heap.
I think that's more than enough to be honest, wasted way to much wonga on all of em.
would do it all again though, well allmost......
