I'd get the 2.0 Mazda 3. Just make it shiny and always clean, and an average person would never know that its an older model since it shares the same body with up to the 2012 models. The 4speed AT was compromised by the manual mode, but take note though that its not that super responsive (may konting lag pa din). Just not sure if it can clock 100kph within your specified time frame.
