by the way, if you do take your car where someone else will wash it, bring some CLEAN quality drying towels for them to use on your Boxster. Never let anyone touch your paint with el cheapo scratch/mar-allot KMart terry cloth towels.

oh and no soap/detergent on the softop ever. (attracts dust #1 enemy)
pre-spray your wheels with a good wheel cleaner before running through the
car wash. I use p21s wheel cleaner, especially during winter/rainy season.
