Does anyone know of an easy way to check whether your car is either the Touring or the Grand Touring for the 2008 Mazda 3 model? I need to know for insurance purposes. As far as I could tell there seemed to be a lot of overlap between the two models in terms of features and my car seems to be about halfway in between the two in terms of what was added so I'm having difficulty establishing which one it is. Is there an easy definitive way like measuring the wheel size or something on the interior to check?
