I had an 07 when they first came out....replaced the windshield with in the first year....trust me its a ROCK catcher...and the glass is one of the softest on the market according to the tech that replaced mine at the time.
According to the w/s replacement tech, nissan has the softest glass. But the FJ is close. I am sure there is a entire blog somewhere on line about the FJ w/s design.
Not impressed with the quality of the plastic on the interior, if you look at wrong it will scratch. And if you add larger tires...it will suck gas like a new born kitten. Enjoy it for what it is, don't count on economy in any sense of the word. Keep your tires properly inflated to help you get 18-19 mpgs on the highway. Easy to do your own oil changes. Dealerships around Charlotte want 32-34K for a new FJ....you have GOT to BE KIDDING ME!! They are high balling....i say if you must have one buy used and certified and haggle like hell.
Best of luck,
