I bought a bakkie from them on the 26th of May … I’ve brought it back to them to few a lot of things within a short space of time and they were claiming from my warranty. It makes me wonder what would have happened if I didn’t take out a mechanical warranty. Now the car has been making funny noises and I’m being told that because I’ve driven close to 10 000km… they will have to charge me to diagnose and fix because it’s a wear and tear issue. I’ve had a very bad experience with the dealership and I wasn’t the only one having problems with them
