I bought an '06 new, and now have 6,600 miles on it. All in all, it is a great little vehicle--tons of power and the torque makes it a hoot to drive. It is actually fun to drive around town, listening to the engine and having fun with the torque.
I have always had large vehicles, so the small space took some getting used to. My biggest complaint is the lack of footwell room, and the seat does not seem to fit me well, although my wife says it's fine.
My best tank was 29mpg doing 55-65 mph and trying for economy. With a heavy foot around town, gets ~21. At 75-80 mph, ~25. There is a thread on L.O.S.T. KJ's about disconnecting the EGR valve, which boosts mileage by 5-10%; some guys report just over 30 on the road. It also changes the driveability for the better, with better throttle response and transmission shift points. Of course, such a modification is illegal for road use, so the thread/modification is called the "O.R.M" or Off-Road Modification.
At 80 mph it has LESS wind noise than my '07 Crown Victoria. One time I got on the freeway, and was of course accelerating to merge with traffic, and was then cruising along with no effort and no wind noise; I thought I was going around 65-70...I was wondering why everyone was going so slow (I was passing everyone)...looked at the speedo and I was doing 85.:smiley_drive:
If you are OK with the small interior space, you'll love it.
