I agree...serious ADD on this thread, its confusing to read.
Anyway, I think its pretty tough to read different reviews from different people on different days on different cars.
The best thing would be to have one person drive all the cars on the same day at the same place...otherwise its all just in the minor details.
Tell you what...if one of you can set up an F40 or F50 next to a 997, I'll be happy to test them out for you. Just give me a holler. I am willing to make that sacrifice.
