I just bought the Mazda 6i Sports sedan and I have no regrets. I considered a Mazda 3; however, I needed a little more room. The 4 cylinder has plenty of power, and is wonderful on gas. The ride is also incredibly smooth. The interior is roomy, however the car itself is easy to parallel park. If you are looking for a fun car that has a lot of class, this car is for you.
Radio controls on the steering wheel, plenty of interior light, lots of trunk space, lots of compartments for items, extra outlet to charge cell phone in addition to the cigarette lighter.
The trunk requires extra effort to close. If you often have a lot of shopping bags, this can be difficult. Daytime running lights and automatic light shutoff should be standard.
