Pontiac GTO
The first year for the modern GTO was 2004, and the car met universal praise from the buyers and the car press. The design was familiar and moderate, but the GTO had the muscle car form and street presence. Under the hood was LS1 5.7-liter V8 with 350 HP and enough performance to be one of the hottest American cars for 2004. The target sales figure was 18,000, and Pontiac sold almost 14,000, which could be considered a success (via Edmunds).
The 2005 model year saw the introduction of the 400 HP 6.2-liter engine and even better performance (0 to 60 mph time of just 4.6 seconds), but sales started to decline to 11,000, and for 2006, the final model year, GTO sold in just 14,000 examples.
