I am selling my '99 GT and considering either an 05 GT or a '99 LS1 Trans Am (stock). The T/A is $11,500.00 with 50K miles, auto and when we G-Tech'd got 13.4 byt we couldn't G-Tech the GT because the dealer came for the test drive Anyways, I'm leaning towards the LS1 because of the price and power. I've been spanked by every LS1 I've ever raced, so I know first hand the insane power they have. On the other hand the '05 GT is brand new, will last longer but costs almost three times as much as the LS1. What shoudl I do?
