Well, I waited for three month before I wrote this review. I wanted to buy either a Civic, Corolla S, Mazda3, or a Scion tC. The Civic and Corolla give you good gas mileage but the they are no fun. Both Mazda3 and Scion tC are very fun to drive. I drove both of them with manual transmissions. The Scion tC is better for couple of reason. First it's a Toyota, which equals reliability. The Mazda is a European car, and at the end parts are more expensive. Second, the Scion just looks so much better. Just tint the windows. Overall I would highly recommend the Scion tC.
The acceleration, exterior (especially the sunroof), iPod aux input, sound system, and trunk.
Improve the gas mileage. So far I am averaging from 19 - 20 mpg. The 23 mpg for city is just not achievable. They should also add a sixth gear. Also, this car has a large blind spot both in the front and back. You will see them if you test drive it. Overall, I still love this car.
