@LimuruBoy: What my bros do is they scan the papers for car auctions and plan to attend them. They don't have a specific auctioneer that they prefer to use. They have their contacts in banks and are normally informed when repossession instructions are issued and to whom the said instructions have been.
The logbook is normally kept as collateral until the balance of the bid price is settled. It is normally accompanied by duly executed transfer forms. It is prudent however for you to carry out your own research to determine whether the logbook is clean (i.e. no caveats).
Get a hold of The Standard or Daily Nation and go through the classifieds. You will always find auctioneers giving notice of auctions. Call them, ask them for the terms & conditions of sale, ask to sight the logbook, and find out why the car was repossessed!
