I've had my Mazda3 for over 3 years now and it has been great in terms of maintenance and reliability. My only complaints are that the ride is too bumpy, stiff and noisy. It does not seem to absorb imperfections well. Also the fuel economy is nowhere near the stated number. The actual city fuel economy it gives me is 10L/100km during SUMMER time and I dont drive crazy or rev it too much.
