Help choosing between cars? 08 civic coupe, 08 scion tc, 08 honda fit, 08 mazda 3?

Hi, im looking to buy a new car. im 19 and i want to make some modifications like an intake, exhaust, and suspension and possibly a turbo, but probably not the turbo. the prices are similar so im pretty much basing my decision on the criteria: performance, mileage, looks, and reliability. please help????
