I found some times for the Grand Prix. The 2004 Grand Prix GT2 can run 0-60 mph in 8.1 seconds and the 1/4 mile in 16.2 seconds. The 2004 Grand Prix GTP Comp. runs 0-60 mph in 6.6 seconds and the 1/4 mile in 15.0 seconds. This is fast enough to beat most family cars but it hardly seems competitive for a stock Mustang GT. Again, I don't understand why the ones I meet are so dang cocky.
