Mazda 6 Sport MPS PRO Infos

hello, we have acquired a mazda 6 mps per. from the mazda dealer with 166ps,160 000km of running power and built year 2002, petrol. and everything that belongs to this 😉 my question is now: does our model have a control chain? is there a list with the equipment features that the mazda has? what do I have to keep in mind? how are the maintenance intervals? have read anything with nem turbo?or was the construction year dependent? ne uplitation of the motors which tooth belts or control chain have? unfortunately could I’m not so busy with the car yet, since our treasure is only coming next week 🙂 we used to drive the mazda 323f ba for 6 years 🙂 was a nice car! I uploaded 2 photos of our treasure 🙂
