Dishonest business dealings

Visited the the new facility in Pretoria east to get a price on my car that I wanted to sell. To put it lightly, it was a very unsettling experience as it became evident that they are dishonest in their dealings. The trade price is R966 400 and retail price is R1074 400, they offered R800 000 as the trade price according to them was R823 000 ! This is blatant dishonesty and no business, no matter how big, will be able to survive if they conduct business in such a manner. I managed to sell for R1050 000 at another honest dealer. I will never use webuycars again and I will advise anyone else to do the same.
