Hi. I am going to buy second hand Volkswagen CC 2.0 2016 or Honda Civic 9th gen 2016 1.6 diesel from dealer who states that all cars come with 3 months warranty, they are fully serviced and all cars go thru 101 point health check. Should I still take the car to other garage to be checked or thrust that the cars need nothing and are 100%? and if the cars are 6 years old with 170k kilometers will they require big investments soon? and what car between these two would You recommend. Thank You
