WeBuyCars .... Terribly Disappointing

We bought a manual car for my son (who is learning how to drive) and after two weeks realised that the car was not for him - he needed an automatic. We took the car back to WeBuyCars (after replacing the two front tires, as we couldn't get it through the roadworthy) and they offered us R39,000.00 less than what we had paid for it, two weeks earlier. We were told that it had "devalued" within the two weeks and that the price they were offering was "book value". We took the vehicle to a private used car garage and managed to trade the vehicle in and get the car we wanted for our son; without taking the massive loss that WeBuyCars said we had to. What a terribly disappointing experience. We will never use them again and nor will we recommend them to anyone else.
