One serious problem with buying an electric from GM is that it has to live down its history. Just think of the comments from people like Lutz. Think of the 50 years where profit has come before quality. When GM went bakrupt for being a petrol shil Obama lopped its head off. GM was whining it could compete because of Unions and because wages and benefits were too high and profit too low. But BMW had 2x the proit and 2x the revenue on 2x the wages and way better than 2x the benefits with much more employee input and a much much more powerful union. GM also killed off the electric car in the 90 (I know electrics have been around since the start.) It made some great electrics just so it could scrap them and say they didn't work. As much as I know every electric helps and this was Musk's plan and as crucial as the Volt was, I'd personally prefer GM went out of business or at least through a complete purge because it can't be trusted- its culture is bad and it would revert instantaneously if there were no Tesla. Its a convicted hard core petrol offender.
