I video taped an 03 Cobra against on 06 GTO. The 03 Cobra smoked the GTO 3 times. Once from a dead stop, the second and third times from a rolling start. The Cobra had a 2.8 pullie and a tune and the GTO had exhaust and some other bolt ons.
Patience
With age comes patience, I can wait to purchase one when the price drops. I will scoop one up off some poor sap who cant afford the insurance or payment!
