I have been using car care products from this site for about four years now. I love their Best of Show Wax, Fine Hand Polish, and cleaning clay. I use the products on my '99 740il and my '70 Cutlass, which has a very expensive paint job on it; have always been very pleased with their stuff. The glass polish also works great and removes all water spots from your windows. They also have an array of excellent cleaning/detail brushes, cloths, wax pads, etc. The spare tire air line they sell comes in handy as I have flipped my E38 spare tire upside down and purchased the plastic storage bin from BMW that fits into the back of the spare--nice place for extra storage. The air line allows you to check the air pressure even though the valve stem is at the bottom of the well.
