"Purpose built" is supposed to make it CHEAPER?????
The whole point of building the Volt using the Cruise as the platform is that they can divide much of the engineering cost for the basic car among not just the dozens of liberal idiot buyers of the Volt, but also the hundreds of thousands of far less idiotic buyers of the gas powered Cruise. If they create a whole car model that's ONLY going to be sold in an electric version, how many are they going to sell? 1/10 as many? That would mean the per-unit profit is going to have to cover 10 times as much of the NRE (Non-Recurring Engineering) costs. How is that going to make the cars affordable?
