Don't promise stuff you can't deliver

My first time buying a car with a well known dealership was a bad experience, I was **** to with promises that suddenly changed after I had signed the contract. We sat down with the salesman, I asked a lot of questions which his answers made me believe I am having a good deal. Never trust salesman from NTT krugersdorp they lure you into signing up contract and you end up not getting what was promised.
