Hey guys! I'm hoping some of you could share some of your wisdom. I have a new 2007 Lexus IS350 that I'm trying to take proper care of. I only hand wash and hand wax the car as I had a bad experience with getting little scratches on the car after a cheap carwash I got once. Anyway, I'm taking the car to the dealer for a service and they typically "wash" the car afterwards by running it through their machine and doing a light vacuum. Their machine does touch the car, so I'm concerned about scratches, etc. Now this is a very nice Lexus dealer and they seem to have only the highest quality equipment, so am I being too anal on this? What would you guys do?
