Insurance companies differ in their classifying of vehicles. The best way to find out if your insurance company considers the G6 or Eclipse a sports car is to contact your insurance agent. That being said the general guidelines is that 4 door sedans or 4 door station wagons are considered family cars. If the G6 is 4 door then it could fall into this category. But if it or the Eclipse have a certain engine type, etc it might be considered a sports car by an insurance company. That is why it is important to find out what guidelines your insurance company go by when rating vehicles.
