So after looking at many estates I am going to get a 2019 Mazda 6 sports tourer 2.2d.
diesel because I do regular trips of an hour plus to Wales and other places most weeks. Should hopefully get 50mpg+ on longer trips.

Had a good look around and can't see anything too common on them to go wrong. Any advice what to look out for or common issues? Looking to get one that's done around 30-35,000 miles. Thank you
