And the seating position is more customizable than you might think. The pedals can be moved back (farther away from you) with the aid of a larger clutch master cylinder (helpful if you have long legs). The pedals can be spread (helpful if you have fat feet). The steering column can be shimmed up or down to give you more knee room, the seat dropped down and back, and tilted -- all to give you more room. Unless you are 6' 5" or taller, or upwards of, ehrrrr, maybe 260 lbs., then you're going to fit. Unless you buy a used car from a guy that had a really different shape than yours, then you'll have to do some fixin'.
