Cadillac's XLR roadster has received recognition as having the best car interior of any 2004 model. The award, given each year at the Auto Interiors Show, picked the XLR after 5,500 auto executives judged it on appearance, functionality, innovation and overall impression. The XLR's navigation system also won an award for its ease of use and integration into the ****pit. Ford's F-150 was the winner among trucks; last year, the Cadillac CTS and the Hummer H2 won their categories.
