WE BUY CARS knowingly sell BROKEN CARS

I bought a Audi A4 1.8T from Springfield branch.From the get go the sales person was gambling with our lives as he put a new tyre on a cracked rim and did not inform me of it,knowing I must travel 1200km back home.Now 3 months down the line the gearbox of the car is messed up with a repair cost of more than half the amount I paid for the car.We buy cars,after numerous complaints logged, is making NO contact with me.It seems like, same as the cracked rim, they knowingly sold me a vehicle with extensive damage as there was also NO damage reports for the gearbox on the DEKRA report. So the question now is...do they decide what damages they include on the DEKRA report so that they can get more money for damaged vehicles.Thus knowingly leaving the consumer in the dark with potential massive repair costs to vehicles.This is not how business should be done. So if you ever want to buy a car from the all so trusted WE BUY CARS be sure to have that vehicle checked by someone that you know and trust, because they, WE BUY CARS, definiatly do not have your safety or well being (physical or financial) at heart.
