CMH Boksburg selling faulty second hand Vehicles.

I am highly disappointed by the quality of the vehicles that get sold second hand from CMH Boksburg. i bought a 2016 isuzu KB250 Double Cab from them 4 months ago, i took the bakkie for the first service since i bought it and they called me to tell me that my rear brake shoes are left with 5%. i would understand if i was towing alot or carrying heavy loads all the time but i use the vehicle as a daily driver and have never loaded anything on it. So they sold me a vehicle with faulty brakes because if you know anything about cars your brake shoes are not supposed to wear so quick. when i brought it up with the manager they told me that they sell all the second hand vehicles like that and if they think they brakes will last until the next service then they don't need to change them. So if i can advise anyone buying a secondhand vehicle from CMH Boksburg please go through the vehicle thoroughly before you buy it. Because you never know your first service might end up costing you an extra R8500 which is what i was quoted for them to change the brakes. you would expect buying a vehicle from a big dealer like this one you would'nt have to worry about something like this but i was definitely wrong. i would not recommend anyone to CMH Boksburg as they very unprofessional and are not willing to help you in any way when you have a problem.
