Bought this car as it had excellent value for resale and was AWD - others tested were the Audi A4 & Volvo S60 - the Jag just seemed like a better value for $$$ - the 3L V6 engine delivers smooth cruising power but has enough pickup punch to pass slower trucks/traffic on the highway. The AWD is great in poor weather and snow (make sure you check to see if its equipped with Traction control - mine was not and feels somewhat like a RWD car in heavy snow - light tail end). Also the name brand: Jaguar - it has a lengthy pedigree and the car is not very common on the road - unlike other executive BMW's & Audi's - which seem to be everywhere.
AWD , navigation system, leather interior with heated seats are a must for longer commutes & trips. Looks - this car is a head turner and attracts a lot of attention in parking lots & at the lights. J-Gate transmission - gives the car a peppier feel when in "manual" mode.
Build quality - suspension & alignments (in the last 6 months it's been done 3 times) - known quality issues with regards to transmission, transfer case & prop-shafts - get one with a warranty cause otherwise its big $$$ to replace.
