I'm tall and find many cars too small for me to be comfortable. This is not too small. It has a lot of space in the front and back seats, and is great on gas considering it's a large SUV.
In early July 2010, I purchased a Highlander Hybrid 4WD and am happy with it. I had read some on-line reviews of the vehicle and knew what to expect in advance of test driving the vehicle. The Highlander rides well and is very comfortable much like a Camry rather than the stiff ride of a pickup. It has lots of legroom even in the backseat and can easily accommodate 4 six-footers. My primary reason for buying this vehicle was cargo space and gas mileage as I have two boys heading off to college. I am happy with the cargo space as can accommodate 5 large suitcases and 3 overnight bags without resorting to the luggage rack. I also moved to a new house and the vehicle, with the back seat folded down, allowed me to many things in advance of the movers arriving. My only disappointment has been with the gas mileage. My Highlander Hybrid was rated for an estimated 30 mpg for highway and 34 for city. My best combined mileage has been 24.7 thus far and I had been hoping for the 26-27 mpg range. This is common with hybrids in that they deliver well under the EPA estimated mileage which I discovered after buying. To fully optimize your results, you need to avoid jackrabbit starts, use your cruise control whenever possible, drive between 45-60 mph, etc. Overall, I am very happy with the vehicle and would most likely buy it again. I would consider purchasing a 2WD version rather than the 4WD for better gas mileage.
Every should switch to a hybrid. The savings in gas are amazing. We traded our Jeep and instantly could see the fuel savings. Our first trip in the hybrid was to the mountains in TN and had no problems on the steep roads to the cabin then turned around and went to alabama right after that. I know hybrids cost more out the door of the dealership so order a used one that has the depriciation already and they are a great value and amazing technology. Dont be afraid when the engine cuts off on its own its supposed to do that it cranks back up when needed thats part of the smart gas saving technology.
