Off all the reviews I have read they just don't hit the experience of owning the Toyota FJ. Every time I drive my FJ I fall in love with it more and more. I'm 40 this month and driving it makes me feel 21 again. Sure the blind spot everyone talks about exist, but it is not hard to get used to. As for the gas mileage complaints, I am running regular unleaded in my FJ. It runs perfect and I'm getting a combined 19 miles to a gallon right now. That is great for this type of vehicle. Really great leg room in the front. I purchased the sandstorm color, and love the color more every time I look at it.
Driving the FJ is my favorite feature hands down. And the looks you get from other people while driving the FJ is better than driving any sports car.
I guess if I had to wish for something, I would have to go with fixing the blind spot, but it is nothing you can't get used to.
