I've had my Aurora Blue Mazda3 5 door for 6 months and love it more with each passing month. The design and handling are the standout features. The interior is one of the best I've ever seen. The hatchback utility makes for a great alternative to SUVs. I nearly bought a Honda Civic Si sedan but the Mazda3 had more overall features that I liked and could live with on a daily basis.
The handling. It's not fast in a straight line but on a twisty road, it's a blast because you can maintain a higher speed than a lot of other cars.
Give it a regular oil filter instead of the drop-in cartridge 2-step oil filter process it has.
