Personally I never really liked the look of the CTR compared to the 172 - seemed too boy racerish - that is until I saw one in silver!!! Pulled up next to it on the A4 (?) and was in a lot of traffic so couldnt play but it did look nice - soo much better than the red and blacks ive seen. Really surprising what difference colour can make to someones opinion. But the trouble is that for the 172 price you dont get such a good CTR inside - i like my comfort and toys!
Oh, and great vid - those drivers are more daring than me, wouldnt get my 172 that close to another car on a track (yet!)
