Just an FYI... I just cashed in on the 20% off coupon while at my p-dealer for service today. Got a p-car cover, p-sun shade, p-rubber floor mats, and oil filter wrench... saved about $70. The floor mats and oil filter wrench were less than what I found on Pelican Parts. The outdoor car cover only cost me $167... seemed pretty well priced. Here's the coupon if you're interested: http://roger-beasley.porschedealer.com/specials/parts/. Note: this coupon is only good for the dealer in Austin, TX.

Just look under the Service Special Offerings in your local p-dealer's website for the coupon appropriate to your location. Looks like the coupon is good until 31MAR.
