For me the Quality/Ability of a Sportscar means a lot more than only being fast at the 1/4 mile. The GT3 has a whole different approach. It was never made for drag racing or driving only straight on. And on the German Autobahn, where you can use the full potential of this car, this car is very fast. Its the whole package of Power, High-Revs, Handling, low-weight and sharp throttle response, which makes this car so special. It was made for the Race-track.

Here is a little video from the Nürburgring-Nordschleife to get a little impression of the Handling. It was on a German TV-Show. (sorry, no American language)

And here the GT3 RS with some phantastic drifting:

And here something for the High-Speed freaks (300 KM/H+) on the Autobahn:

Personally I would always prefer a Porsche Turbo over a GT3, because I like the Turbo-Punch and the massive Torque at low and Mid-Revs. These Porsche Turbos are phantastic cars, can be used for every day, and are real Monsters if they are tuned. Especially at higher speeds these are very serious cars. A friend of mine drives a 996 Turbo, and we spoke about comparing my SLK32 with his Turbo on the Autobahn. This will be fun for sure...
