When I bought my 1998 230K the interior was unsightly. I knew that I could strip and repaint but the hardest part was waiting the 10 days for the paint to come from Germany. I stripped the paint from the worse of the pieces using Citrusstrip. It worked well but after the fact I found out that by immersing in water would do the same thing. After stripping, I cleaned the parts with 99% alcohol and I still had streaks on the pieces. I sprayed the parts with some primer and used a large cell sponge cut into 1.5" squares to apply the Quartz-Sand paint. After 2 coats my pieces were looking like they did when they came from the factory. I even got the parts back in place without scratching the new paint. I did buy a new main center console as the piece was too far gone crack wise.
