My wife has the same set up as you, nice car to take a cruise in. She uses as daily driver, her 2nd, drives 10K year, no real issues.
6 speed on-line is the best source for info, classified's, how-to's, etc, etc. Lot's more Porsche's out there then vipers, so at this site you'll find a ton of info. As someone said Rennlist is good too, but 6 speed is much more robust. As you'll find out from the dealer service department prices, you need to service all you can yourself. Local dealer wants $300 for oil change. Take a look at how to change the air filter, then you'll see why they service at the dealer is so expensive. good luck and enjoy! Mike
