Rented a Camaro 2LT from Avis and drove it just under 1000 miles from Ft. Lauderdale, Fl. Loved the car and had no problems. Top speed (by GPS) was 101 and averaged 24 mpg. Still waiting for Z28 but I am sure that my gas mileage will not get any better.
Walk softly, carry a light saber and drive a ZL1!
