My first trip to the KNP in my own (student) car was in a "rammelkas" of a Volkswagen Fox. It did the job, but it was not comfortable...o no, not at all comfortable....and we couldn't see over the tall grass... (I got rid of the unreliable and uncomfortable Fox as soon as I started earning money...)
Then a few trips in a Daihatsu Sirion - much more comfortable but still too low... (and the ellies don't take one seriously in a lavender-coloured mini car)...
So I got myself a Daihatsu Terios with automatic transmission (the perfect birding vehicle! - you can drive with a pair of bins in one hand

), and have never looked back... High enough to see over the tall grass (only had problems in KTP north of Nossob, where the sand gets a bit too high next to the road in places), fair off-road capability (perfect for the KNP's eco 4x4 trails), light on petrol (in a 'test' against my friend's Volkswagen Polo 1.6L hatchback, it got just about the same mileage (about 14km per liter although the 1.5L automatic Terios is advertised as getting 12km to the liter), and because it is a light SUV with permanent four-wheel drive, it is kind to the environment (in terms of causing less damage to the 'veld' than either bigger and heavier 4x4s and non-4x4 vehicles)! What more could one want in a Kruger vehicle? (okay .... maybe a bigger engine so that one can pull a decent-sized caravan if you're one of the camping fans, but then the fuel economy goes out the window.... choices....).
And it's fun to drive
Only problem I have is with the central locking opening and closing the locks of all five doors every time you switch it on and off... (pain in the you-no-what at skittish animal sightings...)
