The XLR is a two-seat roadster with a power retractable hardtop, built from 2003 to 2009. It shares much of its structure with the C6 Corvette, including the GM Y platform. Its 4.6-liter Northstar V8 makes 320 horsepower and 310 lb-ft. It was the first production Cadillac with radar adaptive cruise control, and it brought Magnetic Ride Control and a head-up display. This example is a 2005 XLR in Crimson Pearl, with an automatic gearbox.
