Put the top boot on my '99 for the first time today -- it's actually much easier than some ragtops I've had in the past. To people who've posted here saying it's a PITA, I can only say you don't know how good you've got it.
The car is black/black with beige interior but came with a black boot. Looks real good, but I think the beige one might look better. I guess it only comes w/beige top even though IMO the boot should match the interior not the top since it's out of sight when the boot is on! I might like to have a biege boot if not too outrageously expensive (which is virtually a foregone conclusion if it's a BMW part ;-) Has anybody priced one of these things?
