Here we go again!!

There just isn't much between any of the following cars, as Sport Auto test results show:

1. 7.46 Gallardo SL
2. 7.48 997GT3
3. 7.48 997GT3 RS (shouldn't it be faster??)
4. 7.49 Z06
5. 7.52 Ford GT
6. 7.52 MB SLR
7. 7.52 Gallardo (original model)
8. 7.54 997 Turbo
9. 7.55 F430 F1

As you can see, 9 seconds separates all of these car, driven on different days, with different tires etc. Just very little difference on a 20+km track. It also demonstrates how difficult it is to lap under 8 minutes.
