I can guarantee you that power is really used on the local roads and highways. especially in a Z06 with over twice the stock HPI had two Z06's that I took to Watkin's Glen for Open Track days. It's really a great time being able to open it up on the straits and coming out of the curves. You never get to really use those cars on the highway.
I WILL say, if You have to pass a group of cars on a two lane highway, those cars will really shine at passing. Track days are the real deal though.
That M3 must be a lot of fun. I'd love to run in a cleass like that, but after 4 back surgeries, if I hit a wall I could be paralyzed pretty easily. Talking to cyclerdoug I'm thinking about getting back into flying again. That's a great motoring hobby that a bad back can handle.
Like I said, the Deep Water are awesome, and on overcast days the PRIZM DAILY is a great lense for that. I am completely sold on PRIZM technology. It really offers a lot if You choose the right lense for the conditions that confront you.
