I live in Australia and was looking at the Sirion for a second car. When checking out insurance, they list two 1 litre models, a standard Sirion & an M100 model. Is there any distinquishable signs on how I can differentiate the two on the actual car? There was no service manual in the car. The car was manufacture in 09/2002 if that makes a difference. Any help would be appreicated.
