Dunno how many of you guys have been in The Carrera range (997). Ive been lucky enough to be in C4S, GT3 and Turbo. C4S- Lovely car inside and out, but as everyone says not that much, if any, more special than S-Line A3 interior. £53k difference should surely get you some sort of space material thats not on an average car. GT3 - The GT3 is also a really nice car, but lets be honest, a typical race track car meant for nothing other than race days. Also obviously for burning every chav in his suped up saxo off the lights without even touching the accelerator pedal. Not that you couldnt do this in any of the other porsches. Losing the two seats and pretty much everything from the interior is a big downer, even if it does mean you get 0.2s off 0-60 time. Turbo - The turbo is basically a C4S with a turbo-charger. The interior is basically the same except for the fact it says turbo on the dials. It does cost 18k thereabouts more, and is it worth it? I think so.... The power is unbelievable and similar to what it would feel like if you screwed a 747 jet engine to your car. 0-60 full second faster than C4S in 3.7. What a feeling ! IMO, the C4S is basically that one step down from the turbo. Its like a ham sandwich without the mustard or 2.0T to a S3. There is a significant gap in power throughout the rev range in comparison. Not knocking how quick the C4S is, but its very noticeable when sitting in a turbo immediately after being in the C4S. The GT3 needs to be revved for a full smile to be put on your face. Trust me it does, however the loss in interior goodies would put any everyday car lover off buying one. The simple fact is you couldnt use it everyday. So for pure pleasure my choice would be a Turbo as if you can afford a C4S why not save up a touch more for the full monty. However if you want to race at a track every other weekend and have no kids or gadgetery know-how get the mighty GT3.
