I bought a Mazda3 GT 2010 in Jun 2010.
Good:
Performance is amazing
Reliability is very good----I've driven for 180,000 km so far and it never down on the road.

Bad:
Price is kind of high---It spent me cad 30200 on road;
Suspension is kind of hard--you will not feel comfortable on bad road
Seat is kind of narrow so that long trip will be easy to feel tired;
Original tire is way to soft---I have to retire all 4 tires at 58000km

Overall I'm satisfied with the quality, performance and reliability but next car I won't buy it again.
