Justin,
I definately get your opinion. Of course the absolute laptime doesn't count too much. Especially if you see the SL55 performing remarkably well, its weight will hurt consistent laptimes and will also put a LOT of stress on the whole car!
I see the Nürburgring as the most appropriate combination of features that you will find anywhere in the world, of course a few of them might be excluded in certain places. Anyways, achieving the above mentioned laptime demands a very good overall car. Therefore not only the topspeed has to be high, you also have to access it, it has to be stable in the mentioned high-speed turns and especially the braking performance has to be superior! None of these features are irrelevant in daily use, since you want to have good brakes, a safe handling and if you buy a sportscar you also want proper power delivery! Right?
Nick, since I haven't driven the CGT I can't say anything about it's driving feel. So my comments don't help anything in this aspect and we have to rely partially on your opinion!
Anyways, I repeat my words. The very first 911 RS (2.7) was very tricky but rewarding to handle. There were quite a lot of people who weren't able to get along with the car. Today the CGT has a similiar character but people are not prepared to appreciate it. Maybe the performance difference to Enzo and SLR (and GT40 etc.) is not high enough to justify its demanding character?
Maverick,
I recall a test, I believe it was in AMS or SportAuto, who tried to do a comparison of CGT, SLR and Enzo. This is the fact I remember the most since I was very anxious to know the Ferrari's laptime!
Ferrari is much more strict with their test cars and the above mentioned comparison of F40 and 959 was quite a unique experience to the crowd!
