First back to the original part of the thread:
LR's in SA are generally overpriced, overworked sheds, unless you are willing to pay a fortune.
Toyota's - 60's, 70's, 80's and 100's can be found but not in huge numbers, but often better looked after. Hilux's aplenty and definitely underestimated!
Nissan Patrols and Navara's, (D22's - old shaped) also seem to abound.
Choice's, (IMHO):
Toyota
Nissan
Land Rover
but do not ignore the other options - Isuzu etc.

speak o Stuart, or his wife Cath, what he doesn't know or can't/hasn't done to a Toyota (or a Landie for that matter), is worth knowing about.
The vehicle - 80 series, fully prepped - I purchased from him was envied by many, and I had people fighting over it when it came time for me to sell.
If in doubt about LC over LR, check out the Poland rover website, the owner a member here, spent a veritable fortune in time, love and money on his Disco, but the lack of reliability turned to to the light and he now drives an 80 - infact I believe he is inor on his way to the Gilf as I type this.
Also look at how many of the companies that run trips out to the Sahara and North/west Africa run Toyotas - mainly 80's. And nearly all I am sure started out as 'LR people'.
Keep on Cruisin'
