I had a Contax TVS several years ago. It had focus problems in that everything appeared okay, but pictures would be hopelessly out of focus - this happened for a few frames per roll. It forced me to sell it - but when it did work, it took beautiful photos - especially color.
I also had a Contax T2 and can mirror the comments above - fantastic. The lens is a killer.
Also, while not a P&S, the best I had was a Contax T, which is an AE-priority rangefinder, though it is smaller than the other two. Excellent exposure system and a lens to die for. They always seemed extremely difficult to find, and always expensive.
