Mynx - If all else fails, you could look into putting it on the train ( Shosholoza Meyl ) and bring it back to Jhb, as they travel from PE to Jhb.
I have never done something like that before, however at a quick glance at their website,
www.shosholozameyl.co.za/car-transportation.html , they mention it will cost about R2000.
You will just need to arrange putting it on and getting it off the train at each station.
Worth looking at if there is no other option.
Mabey other punters have experience in doing this ? Guys, help this lovely lady !!
