The top reason to buy an SUV is for traction control. Well, the technology in this car is phenomenal. Full, split axle 4-wheel drive for mud and snow slopes that some trucks could not even handle. Computer assisted 4-wheel drive for on road use in snow and ice, along with a brilliant ABS system, though unnerving at times, and you can be sure of a safe fast stop in any weather. I also got a special suspension option (one of the few options offered on a Lexus) and I am amazed at how it handles bumps. Riding in this car is an absolute pleasure. Its computer technology is amazing as is its build. Cost is high, but I can say, it's worth every penny.
Handling and suspension, DVD w/remote headphones, comfort and quietness of ride.
Implement the 8-6-4 cylinder technology other cars have in order to get a little better gas mileage. I get a stable 15 mpg in congested highway - local road driving. I top 20 mpg on fast open highway.
