Took the Z to Pittsburg PA this week. 380 miles each way from NYC. Nice series of snake hill's under rain, night and day conditions. For the most part, traffic was going at 75 MPH. On the Z, thats about 2000 RPMs. Plenty of power to spare for passing even during the up hill runs.

The car is a 1996 Z28 with 43K on it. Before the trip had everything checked and the front end aligned.

I averaged 22 MPG. I think thats pretty good for a 12 year old car flying thru the hills of PA.
