I don't have the booklets with me, but the information is quite a lot. I reckon if you bought your car from a unitrans affiliated outlet you could look at the options from them.
The best advice I can give you is to rather phone the various places for quotes, places I can think of off hand:
The company financing your vehicle
Motorite
SA Warranties
Hollard
They have various conditions attached but in general the coverage is similar. If I remember correctly we are paying around R500 for maintenance plan with SA warranties, and around R200p/m to ABSA for warranty on the vehicle.
