I have an '08 FJ and so far it's been a great daily driver. We needed another SUV after our '98 Tahoe took a shit and I bought the new FJ instead of a new Tahoe purely because of the price, new Tahoe's were 40-45K, I got the new FJ for 27K out the door.
I drive the shit out of it on the road, ask dpdsurf, chino63, darksoul who can all attest to my amazing driving skills. It's been offroad a few times and has done great every time even with the rear hitch rack and the rig being filled to the brim.
Pros:
Very durable interior that you supposedly can use a hose to clean.
Plenty of horsepower to handle a fully loaded rig to travel at 80+ MPH. Tow capacity is 5K.
With the roof rack and rear hitch rack I can carry more gear then my old Tahoe and still get way better gas mileage.
Stock offroad capabilities are more then capable if you ever need them.
My cons or cons that my wife has:
My biggest complaint would be the design of the front doors and the seat belt system being integrated in it. There is a big plastic molding at the back side (towards the rear of the truck) that acts like a wind scoop and when you have the side windows down on the freeway or at any decent speed it directs the wind right into the side of your head. Because of this even on the nicest of warm weather days you won't be driving down the freeway with your windows all the way down.
Front visibility while at a street light poor, basically if you are the first one to the light then you won't be able to see the overhead street lights unless you are short or lean forward. Not really a big deal because I just look at the street lights on the side.
Rear and side visibility sucks and not much you can do to improve it so you just have to get used to paying attention to your surroundings when driving on the freeway and changing lanes. It's not that big of a deal for me.
Rear side windows don't open/roll down or do anything. For $400 you can get some aftermarket side windows that open from
Toyota FJ Cruiser Windows | Vent, Side Windows FJ Cruiser | Toyota FJ Aftermarket Windows
My wife hates that you have to put 92 octane gas in it, I could care less. I'm very happy with the horsepower and think it definitely warrants the slight extra cost of premium fuel. I have a lead foot all the time and I get roughly 17-19MPG.
