Have had the car for over a month. Mileage has been running about 42-44 commuting to work. The navigation system is not worth it, bugs and out of date database. Entered B of A, selected one a 1000 miles a way. The hybrid battery needs to be about twice the capacity, runs out of steam too soon, any grade of more then 1/4 mile, then the engine revs up, which is noisy. Road noise is not as bad as some have commented on. No XM, should be standard with Nav, can be bought as an accessory but expensive. Worst sounding stereo I have had on new car in many years. Interior materials are flimsy and cheap, push my hand against the door and the material caved in and then popped back out.
Gas mileage, better driving experience than Prius.
Standard XM w/ Navigation system along with real-time traffic. Larger hybrid battery. Remote start. Better speakers. Electric driven air conditioner, salesman lied about the AC working when the engine stops while stopped a light. Rear view camera, rear visibility is not good.
