Who does good restoration work on seats? I have a '98 M3 coupe in Estoril Blue with Mulberry interior. I would rather have the front seats restored than get aftermarket seats. Anyone know who will do this at a reasonable price with good quality? I'm located in East TN so something relatively close would be good. I've heard pretty good things about Korman and I plan to reach out to them, but wanted advice from any others that may have experiences with other places.
