My wife found a vehicle she was interested in at their Website, We stay in JHB, so she ask what can be done sow e can see the vehicle, Test Drive it and possible purchase it. After intense negotiations, Vanesh proposed that if we pay deposit in their account he send driver up to Joburg for us to test drive it, Immediately After we paid the deposit, they started to change the stories, Charmaine contacted my wife and told her that they cans send the car if we are not \committed"to buy it.. We asked How we can be committed without seeing and test drive the car"
