Although the initial $76,000 tab was almost twice that of a base Corvette coupe, the XLR got here with most every amenity identified in the automotive world: power every thing, heated/cooled seats, OnStar, a navigation system, "good" cruise control that routinely maintained a safe following distance, and Cadillac's new Keyless Entry system with engine-start button and no exterior keylocks. The one choice was satellite radio, and that became standard for 2006, together with steering-linked xenon headlamps.
