Mazda 6 GG Combi

Good day, how are your experiences with the Mazda 6 GG GY ? I am currently not sure about the Mazda 6 GG Combi or GY (not for long). Car has 160tkm by time currently no ÖL engine runs like hell am Mega surprised. How is the experience in terms of longevity seen on engine and body. Engine I have the 2.3l 166ps front drive with 5 gear manual.
