Faulty Second hand Vehicles

<p>I purchased a vehicle (Polo GTI 82300Km on the clock) from VW Ballito in March this year which i paid cash for, the car was not even a day old and the problems started, after standing for almost a month the car was returned to VW in Ballito and they gave me a Golf 7 TSI Bluemotion (108 000Km on the clock) plus i had to pay in a cash difference, two day later i picked up that the car was using oil (2 pints the first time and 3 pints the second time) in a matter of 1000km and notified them of the problem which i was asked to drive down from JHB to Ballito so that they can do an oil pressure check on the car which came back the rings were damaged, now i have been given a Polo Vivo which is the third vehicle from them and for the third time i have to pay on the road costs which i feel is not my problem as they are selling s****, i have within 3 months lost R30 000,00 due to all these cars and sour deals, please people watch out when dealing with them. </p>
