Why it's a winner: Bang for the buck, last-chance Pontiac
General Motors is dropping the Pontiac brand as part of its bankruptcy reorganization, but while they last, customers are buying up the remaining stocks of the Pontiac G8. The G8 is a modern successor to the legendary Pontiac GTO. It's relatively tame with the standard V-6, but it can be ordered with an optional V-8 with up to 415 hp, the most powerful Pontiac ever. Surviving GM dealers will be able to service the G8.
