No problems so far (2 months owned), although the front bumper hits a lot and is breaking from the bottom.
I bought the car based on looks (I'm from LA), and that's all I pretty much got. The car max out at about 105mph, I expected a little bit higher. I haven't tested the 1/4, I fear the rubber band (timing belt) might break. The car wastes a lot of gas for a 4 cylinder non-turbo.
The car has great handling, in the 110N fwy I can do around 70-80 breaking a little sweat, the limit there is 40.
Mods: the car only has a cold air intake system, this "sports car" is gonna need a lot more mods for me to call it a sports car.
Overall the car looks great and runs good so far, I'm satisfied with the car and looking forward to adding a few aftermarket parts (wheels, ground effects and sound system), not looking forward for all the performance mods needed.
Maybe if you didn't buy the lowest model eclipse, you wouldn't be complaining about performance so much. You buy crap and you get crap.
