The fastest I drove mine was on the way home from the dealership. It was a warm day, my first convertible, in a new car that sits up MUCH higher than my previous Saturn(s).... I was just keeping up with (ok, occasionally passing) the traffic on the thruway and enjoying the ride. Then I looked down and went "CRAP!" as I saw I was going about 85ish!
During that drive home I decided I
really needed to get cruise control, or at least some form of governor. I was happy to discover the only cruise module available at the time, the MDC module, had both though at a steep price. I can tell you it was worth the price vs the tickets I'd have gotten by now without it though.
