I've owned this car for 10 years and other than regular oil changes and regular maintenance I have only spent $250 for on-board computer connector that was replaced. It's time to do the timing-belt change now, but that's expected with close to 100k miles.
Reliability is the key with this car. People get impressed how good it looks after 10 yrs and there are no squeaks inside the car.
The only improvement on the Acura line is that they should start building more aggressive cars similar to Lexus ISF line. You have the quality now is the time to compete with BMW.
