 I've had the car for 3 months and have over 4,000 miles on it.  I am tall (6'6") and I have plenty of head and legroom and an adult can fit comfortably behind me. Gas mileage is less than the EPA rating by quite a bit, but it's still very good.  Average mileage has been 32 mpg.  On a level freeway at 65-70 mph, I get around 36-38 mpg (approx. equal to EPA). With hills the highway mileage drops to about 30 mpg. On city streets, with lots of stop and go, the mileage is in the low 30s (much less than EPA).  The best mileage is achieved in slow moving or stop and go commute traffic, where I have gotten above 50 mpg.  I don't regularly commute with the car, but anyone who does should have a hybrid.
