I recently bought an SLK320 from 2001 as a used car. It is my first Benz and is certainly a pretty thing. I'd like to do the best to keep it in as perfect condition as the modern world will allow. I'm wondering what I should be doing about those nice leather seats. I asked at the dealer and they said to just use soap and water to clean the leather and keep it looking nice and supple. I had bad luck with the leather seats in a BMW 3 I used to have. By the time I started paying attention they were cracked, and just got worse as the years went by. I'd like to avoid this with the new car. Any suggestions as to what to do and which products work best would be much appreciated.
