I have a '22 preferred that I bought last May. Only have 3500 miles on it -- I was getting about 24.5 miles combined city/freeway (mainly city) last summer or so. Freeway mileage seemed to hover around 31-ish. However, I've noticed my mileage has dropped to around 21.8/22.3 the last couple of months, perhaps due to the colder weather. I typically use manual calcs, since I notice the dash mpg occasionally tends to differ from the display screen by approx 0.5. Hopefully it should do better when the weather warms up.
