Based on the Chevrolet Corvette, the 2009 Cadillac XLR-V is defined by sharp-edged styling, an exclusive interior, and unique suspension tuning. The Chevy platform upon which the retractable hardtop roadster is built provides the XLR-V with a strong sportscar foundation. Since its introduction in 2004, the Cadillac XLR has aged well, but despite its striking exterior profile, the vehicle's interior isn't quite up to the standards of many rival luxury coupes and roadsters, and it needs further refinement.
