Which aftermarket warranty provider do you recommend?
I don't know the exact details, I see its from Innovation Group and seems to be called "Motomend Choice P-O 2 year warranty Opt 1"
A friend of mine has had this on a few of his cars, I believe you get a total sum which can be used for all covered parts and it is not limited to a certain spend based on the type of part. ie. you are not limited to R20k for the engine or R5k for the cooling system. It all comes from that lump sum (I seem to recall around R75k, but I could be wrong). If the full amount is depleted before the 2 year period, then the warranty ends.
If I am not mistaken there are some forum members who have used or suggested this, I recall seeing some info on it around the forums a while back.
