I have owned the IS 250 AWD going on a year now, and I still love driving this car!! Performance is great and I find that the AWD version handles very well, and living in CT, the car has done well in the snow! For the money the 250 has many luxurious features, but does have a some flaws! I had to have the car seviced twice to try and fix the popping noise from the dashboard and the rattle from the sunroof. Dealership was great and had a fix for both issues. The others would be the jumpy transmission at low speeds, first and second gear and the lack of room in the back seat. Overall, the IS 250 has delivered and I'm very happy!
AWD, heated and cooled seats, Interior design, exterior design (best in class), keyless entry/push start, audio system.
More back seat room, fix the rattles in the interior, provide a better stock tire, folding seats.
