The new Pontian G5 GT is based on the Chevrolet Cobalt introduced in 2005.
The 2007 Pontiac G5 base model is actually on sale now and features a 148-hp four-cylinder engine. A CD player and spoiler come standard for $14,995. There’s also a GT model that features a larger, 173-hp engine that starts at $17,795. While the base model starts for roughly $1,000 more than its Chevy sibling, the GT costs slightly less than the comparable Cobalt SS.
