I might be in the mrket for a new car next year and two of the reasonable choices in my price range are the Saturn Ion and the Cevrolet Coabalt. (Of course another option is to buy a bigger, safer higher-end vehicle used, but I want to go new if I can; I've fought most of the used car battles over the years, though for the most part I'm satisfied with my current Saturn SL2, bought used with 30K miles in April 2003.) Anyway, I've been looking into both cars online and I was struck by the many similarities or identical features between the two, even considering they are both compacts made by GM. Then of course I read that they are built on the same platform and the light bulb went off.... What if any are the key differences between the Ion and the Cobalt? Is anyone out there in the sane boat as me: looking at both cars and scratching your head? Anyone driven both? Thanks in advance for any advice. Regards, Eric M
