I know this is gunna cause a HUGE arguement but i dont care, lol. My personal experience is that its a drivers race against a 6.0 GTO. I know this cuz my L has beat several 6.0 and several 5.7 GTO's BUT its an auto so it doesnt take much skill to drive. ITs a very close race for me though. ANy mods on the GTO and I dont stand a chance BUT if there stock I can pull about .5-1 car on them. I raced a Mach1 and he got me by about 1.5 cars but he had intake, exhaust, and tune so...... Anyways Flame on, believe me or dont, IDK. Noone ever does, lol.
Lightning trap speed: 102 mph

Add in the fact that you're driving an auto...you're right, I don't believe you.
