Comparing across wagons, the Saab 9-5 was one of the sportiest models, second (possibly) only to a BMW wagon. My 9-5 wagon is black with alloy wheels and a black leather interior. It has the "Sport" package and is very "sexy".
My 9-5 wagon produces 260hp out of a 4 cyl turbocharged engine. Put the shifter in "Sport" mode and the acceleration is amazing! Shifting and acceleration are very smooth. The car corners fantastic and is great fun to drive.
My 9-5 came with full leather interior, a CD player and a built-in nav system. It also has driver & passenger power seats, backup guidance and several other minor but unique features. The one negative is a lack of cup holders (one built into the dash).
