Changing oil on a passenger car is not as easy as SUV or truck. With low ground clearance and hard to reach oil filter in tight spot justifies for a professional service.
The Mazda Mazda6 changes all of that. The drain plug can be reach with my 6 foot body frame, the filter is right behind the radiator and it points straight down with a large cut-out in lower splash/aerodynamic guard.
The zoom zoom makes car driver a car driver and loving the idea of making car serviceable by an average Joe.
