I have a lot of Porsches, around 12, I think. My fave is the '09 911, and the '16 911. The Carrera '04 is probably the easiest to drive fast and is very good, a real Mid Rear car and with a water cooled engine. The earlier 911's were air-cooled engines BEHIND THE REAR AXLE, which makes for interesting tuning challenges for most. That said, the '09 911 is a R/R but properly tuned it is really a fun car on the Nordschleife. I recommend Praiano for very well tuned Porsches of all vintages, he just seems to have the feel for supernatural tunes on these cars. If an old guy like me can win on the Nordschleife at the age of 79, driving the '09 911, well, go figure.
Cheers, Pete
