The standard car should have one set of twin exhaust pipes exiting on the passenger's side. Anything different is an aftermarket exhaust system. The crucial thing is the sport button which when you press it should sharpen up throttle response. If you have this, it's the 170 Q2. Anyone can stick the white coverleaf badges on the wings so don't go by that. If the car is an SE or special addition it should have headlamp washers, heated seats and Blue Tooth.
