Porsche had an automatic way back in the 911 called a Sportomatic. Many of the car magazines of the time enjoyed the performance of the car with this transmission.
I have to agree with Ronzi's posts on the Tip. It isn't the anti-christ - it's a viable way to move your Porsche around. I have had a 98 Tip Boxster, a 57 356 Speedster 4 speed manual, an 03 911 C2 Cab 6 speed, and now an 03 Boxster S Tip over the last four years. The 356 had a progressive clutch and was easy to drive around town. The 911 had a heavy clutch and was a bear in around town traffic as the clutch needed a rev blip to settle into gear and go without stalling. If I only lived in the country or on a race track, the 6 speed was fine. It was not second nature in heavy traffic and never would be. With SUV drivers pulling up to within an inch of you on every stop, you couldn't just be lazy with the clutch and let it slip a little to engage. I don't miss the 6 speed one bit. Different strokes for different folks. I'm sorry if some people feel that a 5 or 6 speed only equals a sports car. A sports car is about handling, steering feedback, carving a line, and many other things. Matching revs on down shifts is slick, but it isn't the only thing in the sports car portfolio. A lot of people have manual transmissions in Hondas and Toyotas and most of those will still be boring sedans at the end of the day, despite the hallowed manual transmission. Enjoy your choice, I'm enjoying mine with the Tip and don't buy the manual tranny argument
