From: http://www.answers.com/topic/sports-car
"A sports car is an automobile designed for performance driving. Most sports cars are rear-wheel drive, have two seats, two doors, and are designed for precise handling, acceleration, and aesthetics. A sports car's dominant considerations are: superior road handling, braking, manoeuvrability, low weight, and high power, rather than passenger space, comfort, and fuel economy."
A monaro certainly doesnt have 'low weight' so NO i dont classify a monaro as a sports car!
