I daily drive mine, but probably 10 miles a day. To be honest though, I rarely take it above 3k rpm during the day. But when I'm driving at night and the roads are clear... (and when a ricers have their windows down)
Mine is a daily driver, 64 miles round trip to work and back. I don't beat on it, but it's exposure to the FL sun is very apparent. It has somewhere over 200k on it. Odo stopped in April '05 at 166,953.
