Hmmm. I still think American cars suck. I only like the Caddy CTS. I have not driven one yet, and honestly it was not a consideration when I was looking. My wife got her Lexus IS250AWD instead. I admittedly bought my Yukon this year because of all the rebates. My poor 22RE could not tow the boat.
American automakers have a long way to go. It's not 'will they last' but 'can I stay awake driving this turd'.
