The GTO was a sales flop, if it was not then they would still be making it.
Funny, there was a contract struck between GM, the UAW, and Holden to build these cars for 3 (Three) model years, at a limit of 18,000 units per annum.
Three model years =
1 - 2004
2 - 2005
3 - 2006
After which time, the future of any domestic GTO would be based on the availability of a future Monaro. Since GM was bringing the GMX282 platform to market for the new Commodore, Lumina, G8, etc, in effect, retiring the GMX281 (which the Commodore, Lumina, Monaro/GTO were on) as of 2006, Holden decided to no longer make a 2 coupe version on the new 282 platform called the Monaro. Hence, no Holden Monaro, no Pontiac GTO!
Please get the facts straight before making absurd comments like "If it were successful, it'd still be built!"
You can't sell what Holden isn't building anymore, right?
