Got a 2003 sl500 for the wife. It has higher mileage than I would have liked, but hope I got a good deal on it. Waiting on delivery. Any suggests for car care products? I was wondering about cleaning the Ventilated seat in particular. Didn’t want to stop up the holes with a leather paste product. It also has a little "butt rash" along the bottom edge of the side bolster from getting in and out. It’s the black designo, I was wondering if a little dye might hide some of it.
