G5 prolly, same thing as a cavalier/cobalt
but in no way they are bad cars, i need to get a vid of the local GTO sometime, running about 7s on the 1/8 mile N/A, he just got done building it, cant wait to see it at 1/4
only time i ever heard an 06 gto sound bad was when one ran magnaflows, sounded like a pissed off kazoo
sad part is you take off the spoiler and they do resemble a cavalier in a way, just a lot bigger
i've had to grow on 1/8th mile tracks since that is the only one around me, the closest 1/4 is about an hour away
oh and another thing about the GTO, we sometimes do these mile long highway races and it can hit about 160 easy
