I hit 1,000 miles today and decided to push it a little, running up to 5000 RPM. I ran into a guy in a new G35 and I must say I was impressed with the car. We left the parking lot at the same time and it was a very close drive down the road. He has 260 HP and I have 235 HP but it did not seem like a real difference, although I am sure we were both a little conservative dealing with new vehicles.
