2005 Pontiac/Holden GTO 14,500 miles and counting.
6.0 LS2 warmed over: Longtube Headers to high flow cats to full 3 inch exhaust with crossover, Ram air Intake, Reflash, and dyno tuned. 430hp.
rear leveling springs.
6 speed Manual
I've only owned about a month, replaced my Targa as daily driver, kids growing fast and needed more rear legroom, backseat is actually decent for a coupe.
So far zero needs, but gas mileage is certainly dependent on right foot. I drive 14 miles each way to work, mostly city. 16mpg in stop and go if I'm nice. 24 highway.
Very happy with mix of comfort and power, looking forward to road trip.
One letdown is a small trunk and rear seats that don't fold or even have a pass through.
