I have had many high performance cars in my life, including a 2001 BMW M5, a Porsche GT3 and a Benz E55. The Jag "R" is the best. The M5 would beat it 0-60 (barely) but jeez, the Jag just FLIES for an automatic. The transmission is just awesome, the seats are SO much more comfortable than the hard ones in the M5, and the suspension is absolutely just right for me. Besides the nasty-fast accelleration, the brakes are fantastic. Definitely recommend this wicked, elegant vehicle.
ENGINE, elegant, tight body, seats, brakes, and the supercharger sound.
Big, toned loud exhaust. Hate the dumb big flip-keys; I use the green valet one. Honestly, no other improvements.
