I would say that you have to not just ask but check that all is well. Before you buy secondhand it is wise to get the AA to do a check on the bakkie. And remember NEVER TRUST A SALESMAN

they will tell you what you want to hear just to make the sale.
For R280k you can buy what ever you want second hand. So go and see what you want go around and test drive all the brands and then decide. You can get a relatively new fortuner or a Land Cruiser 76 Im sure if you wait a while you can get an Amarok, ford, nissan or isuzu. Most top brands will reliese their new models soon (This year, ford, next year, toyota.) then the prices of the second hand ones should drop a bit.
All landies leak through the panel gaps,
Toyota's roll over on gravel

(just change the shocks and throw the general grabber tyres in the fire)
You can get a draadkar (kids toy car made from wire) to leak oil with a ford badge

(I drive a ford)
Isuzu's sound like tractors
Everything japanise is appliances according to the Americans (Jeep drivers)
Just a few of the jokes Okie referred to:
* Spietkops skud jou hand wanneer hulle jou 'n spoedkaartjie gee. (Speedcops shake your hand when they give you a speeding fine)
* Hoekom het meeste Defenders jerrycans en gasbottels? Sodat die bestuurder kan koffie maak terwyl hy wag vir 'n insleepvoertuig. (Why do defender drivers carry jerry cans and gas bottles? So that they can make coffee while waiting for the towing service)
* Landrovers het die beste brandstofverbruik van alle 4x4s. Hulle word altyd gesleep deur iets anders. (Landrovers have the best fuel consumption off all 4x4's, they are always towed by something else)
* Hulle sê 90 persent van Landrovers wat gebou is, is nog op pad, die ander 10% het hulle bestemming gehaal. (They say that 90% of landrovers that has been build are on the road, the other 10% made it to their destination)
* Hoekom noem landrover hul modelle, 'n Reeks 90, Defender 110 ens? Dit is die topsnelhede. (The reason why landrover name their models 90 and 110 is because it is their top speeds)
* Jy breek nie n Landrover nie..... Jy koop hom stukkend. (You don't break a landrover.....you buy it broken)
