Will Pandit do a good job of cleaning the interiors of my Corolla too. It has done 38K, is very clean (I do it myself once every 1-2 months), but a professional work may ease off my work for some months. My eye (I can spot even a minor black tinge) sees things that my hands are unable to remove any longer.
Haven't had first-hand experience with them, Vasudeva, so cannot comment. But based on several reviews, Pandit seems to be doing some outstanding paint jobs. I can't recommend any interior specialist to you as the ones I know are all based in Bombay. Sorry!
