The folks over at Autogespot happened upon a not-so-regular Jaguar XK with factory plates running around town and they're not sure what it is. Could this be the mysterious Jaguar XKR-R that apparently showed up at the 'Ring a year ago and then disappeared? The XKR-R was supposed to get a 500-horsepower version of the V8 and other super-luxo-car upgrades. Now that there's no pressure to avoid encroaching on Aston, could the super sporty Jaguar XKR-R become a reality? Only time or a loose-lipped executive will tell.
