I am thinking about buying RX300, my only concern is that I have a drive way of 150 ft long and about 25 degree uphill. Usually I didn't have time to clean the snow before run the car over it. My question is that when the driveway is covered with 3-5 inches of snow, can RX300 easily go uphill like that. I used to have Jeep Cherokee which could not go up. My wife had Mercedes ML320 which went up fine. Anybody has similar situation? Thanks
