I own this car from brand new, top of the range at that time plus all extras and full leather seats, the car has a little rising oil because the normal build-up carbonisation, and Im still doing 60 ++ mpg with the premium diesel but needs a good clean. The main dealer asked me 3000 quid just to open the manifold and clean up the system, obviously they are more interested to sell brand new cars them fix them ... This car only fail the MOT once, because a broken ring, in 180k miles never ever had any cheap diesel always Premium quality diesel and always original oil from the mazda .. Been told many time the engine is in mint condition for its age, if you are interested to check and read the engine with your tools / computer or any other machine, Im very happy with that .. For those o understand cars, cleans up etc, this is a great car to do a lot more miles for 20 quid tax road a year...
