Pontiac sucks - but yes they do have a few modernish cars that have been good, the recent GTO (I hate the old one) the G8... basically the ones that Timothy mentions below.
They look sick sold as Chevys.
The El Camino won't sell sadly even though it probably makes more practical sense than a truck; that that's probably why Pontiac didn't sell the Sport Truck. The G8 as a Malibu would be cool, but the Malibu itself is supposedly a good car and maybe they want to retain the G8 as a more sporty image rather than in Australia where it is both common trooper and extreme performer. I really really hope that the G8 survives as something under Chevy - Jalopnik mentioned it too but they said it is doomed to fail - they suggested a Camaro SS Sedan.
I thought the Firebird was ugly - I'd take the Camaro any day over it but the rest are all cool and definitely good cars. Compare the amount of good cars with the amount of crap cars they made though and that's part of why they are gone. And badge engineering - that is a devil too.
