I have no faith in any dealer, be it car or bike.
Bought a new bike at Wayne Heaseman. When I got home I noticed the front right indicator has a deep scratch mark on it. Probably a tie down or something. Said they will have a look at it on the 1000km service, only to be told they need the bike there for the whole day to check the indicator out. So they will attend to it at the 6000km service. When I told them it is no good and I needed it fixed sooner, they arrogantly ask why can't I wait till 6000km? My answer was, I bought a new bike and I expect a new bike. Waiting for their call this week, but I am not holding my breath.
On my bakkie, GM dealers are just useless.
My bakkie went in for a new petrol pump, so they droppep the tank and fitted the new pump. Got my bakkie back, but when driving the right rear wheel brakes a lot more than the others. So much that the paint started bubling.
On further inspection, it turned out they never tightened the bolts holding the steel straps, holding the petrol tank. So the bolts came out and the fuel tank was lying on the handbrake cable!!!

On other occasions the oil filter was not tightened, brake fluid all over the wheel arches and firewall, I could go on but I will refrain.
