Given the situation GM is currently in, and how they have no choice but to sell off the bullshit brands they own, i'm sure their market shares will plunge. Leaving Ford and unfortunately the transplants to prosper. So they may not outsell the US makers yet but face it, it's coming. And if it weren't for the situation the US makers are in, I'd put my money on the malibu for 09. Who knows if GM will be around to launch their Volt. So, only time will tell.
