Back in 2007, my dad bought one, and then my sister bought it from my dad a few years later. At first, it seemed like a great value for what you got in the package, but over the course of ownership, it turned into a total POS. Some observations:
-It went through 4 sets of tires and 3 sets of brakes in about 75k miles, which was not impressive. I personally did brakes on it twice, and it didn't like aftermarket brakes. The rear rotors made contact with something on the inside of the rotor and I had to grind the brand new rotors to fit the car. Yes, they were the correct parts.
-The car was slow and felt super heavy. I hated the seating position and could never get comfortable. Also, the rake of the windshield became annoying, and unless I did the "gangsta lean" the view was distorted.
-The stock "Pioneer" stereo quit around 50k miles. I put in a JVC double DIN after that, which was relatively simple.
-One day, my dad was borrowing the car again from my sister and he went to open the roof. The mechanism bound up, and SHATTERED THE ENTIRE GLASS ROOF. It took months to get it fixed, and a fight with the insurance company to get them to cover it under their glass coverage. Basically, the whole roof had to get replaced. I think the bill ended up being over $4k when all was said and done.
-The trim above the license plate that houses the liftgate button broke off and had to be replaced at the tune of $150. Every single one of these cars does this. If you see one and it's not duct taped on, that means it's already been replaced.
-The back seats recline, which was kinda weird but cool. You could fit two adults back there and it was kinda comfortable.
-They hold their value pretty well. My sister got a very good trade in value for it when she got rid of it. That may be out the window with the demise of Scion, though.
-Gas mileage is terrible. I remember my dad getting around 22mpg out of it no matter what and being disappointed. At the time, I was getting more than that out of my heavier, tuned WRX that had AWD and made close to double the power.
I'd say that if you want something with sporty intentions that's reliable and efficient, definitely get something else. If you want a pretend "Tuner" car to stance, cover in stickers, and sit in a parking lot, this is the one.
