I am thinking about buying a 1995 SL 500 and have test driven about 4 of them so far, including an SL60. I have been struck by the different feel to the accelerator pedal on these cars - some have a decent, firm feel to them, and others are so light it's hard to tell when your foot is actually in contact with the pedal. All of the cars are of similar mileages (40-60K). Is it possible to just 'tighten' the pedal to restore the decent firm feel I actually prefer, or is this symptomatic of something amiss? Any responses welcome.
