I own a stock shift DMC12 that was located in Arizona until September of last year. I replaced my AZ drive with something Red and sporty looking, it has a chromed shifter. I parked this in the sun for about an hour in September 2002, in the low desert, the temperature was about 100F. When I got in the car to drive home, I could barely touch the shifter, I learned to shift real fast! I prefer to drive around town with one hand on the shift, not that day. So speaking from experience I can assure you that I never experienced the same problem with my stock shift in the 6 years ive owned the DMC12.
