Great economy for a 5.7 liter LS1 V8. I averaged 17mpg and I drive "agressively." The sound system was great, and even with sort of higher mileage, nothing was wrong with the car. It had previously had some leakage at the rear end, but it was sealed and I never heard from it again.
Monsoon sound, leather, 305 hp, (along with that V8 snarl) auto headlights
Fix the seals on the windows. They leak bad in the car wash.
