i want to get a new suv with 4 wheel drive. my current suv does not have 4 wheel drive. when i purchased it, it was 6000 less than a 4 wheel drive model, i now regret that decision. i don't really like the new 4runner....so was thinking the highlander. i rarely off road, the 4 wheel drive will be for off roading on the beach at pismo, oregon beaches, and more importantly, canada in the winter. 4runner - true 4 wheel drive highlander - a purported "full time" 4 wheel drive system i've read reviews about the full time system and they generally are not positive. any thoughts?
