GM Vice Chairman Bob Lutz has pointed to the Pontiac Solstice as the model for global parts sharing and its role in keeping development costs down. Developed for just $230 million to $260 million, the low-volume vehicle's cost was kept strapped down by engineers who were able to dig through the parts bins of GM brands globally. The donors included an engine from GM's global small-car family, climate control vents from Fiat, backup lights from the GMC Envoy SUV, 5-speed manual from the Cobalt SS, and even the cup holders from the Saab 9-3.
