Tow bar - buying in Cape Town area ?

[LazyTrailRider]

 It also seems the more complicated the electronics, the more expensive the towbar.

 

Yip, that's exactly what it boils down to. Many modern cars have highly complex electronics. If you look at what they do (things like PDC, reversing and top-view cameras, blind spot monitoring, lane assist, automatic high-beam adjustment based on camera input, etc) it's not surprising.

Thanks for comments guys. I have a Kia Sportage and the agent has quoted R8k. 

 

Of course they advise that the vehicle's warranty could be void if anyone besides Kia supplies and fits it. Suppose all dealerships 'threaten' in this manner.

 

Damn!
