2006 Jaguar XJ-Series XJ8 4dr Sedan (4.2L 8cyl 6A)
Jaguar got it right with this car, I have seven, including sports cars like Honda S2000 and Porsche Boxster, and American muscle car classic Impala SS -- the Jag does it all, quietly, composed, and quick. Can't imagine a more responsive and comfortable vehicle.
Comfort, quiet, class interior, quick responsive power and handling. Very economical with relatively low weight and good aerodynamics.
The dealer labor rates and practices are out of line, replaced brake disks (instead of simply turning) with exorbitant parts prices -- thank goodness the 2006 Jag V-8 and transmission are pretty much bullet proof.
