I'm about to drive across Morocco over the Atlas Mountains and into the Sahara desert with a hire car ;)

Given the hire car process I have no guarantees on the make/model of the car I will get but suspect given the road conditions and distances I will be driving it is a matter of when, not if I get a brake down (I'll get road-side assistance with the hire but it could be over 24hours away).

As such I'm keen to lean how to undertake basic roadside repairs before I get into trouble.

Can anyone recommend a UK based crash course where I can learn elementary roadside repairs?
