Christmas came early last week as we got the 2008 Jaguar XKR Convertible into the CNET Car Tech garage. The supercharged soft-top version of the XK is currently the most expensive car in Jag's lineup, and our tester came with a price tag north of $100,000. For that kind of money, we were expecting a lot, and the beautiful Big Cat didn't disappoint. The XKR comes with blistering performance thanks to a blown 4.2-liter V-8, as well as some advanced tech features, including as-standard nav and adaptive radar cruise control.
