I've got 130k on my early on production 95 and normally I shift around 3-4k rpm but I do run it out to about 5.5k rpm, I only go to red line every so often as there isn't much nore power above 5.5k rpm
I am not always easy on the car, had it since 83k and it has been an amazing car, hell I had emission testing done today and the numbers were so low I think I could run with out an exhaust sytem and still pass
