So is Casper still going strong? If I recall correctly we bought our 2009's around the same time ... my Reg No is DN 75 xx GP so registered just a few days before yours. A mate of mine went to test drive a car like this in Nelspruit before I bought ... believe it may have been the one you got?
In the end I bought a car from Upington, about 40 000km more on the clock but R60k less, and fitted with dual battery system, 40mm suspension lift, load levelers, bash plate, seat covers and that infamous Diesel Torque chip. My mods were much more modest than yours ... roofrack and Aux input only. Now on 258500 km (not 270000 as I said in the other post) and going strong as ever. Still miss my V6 Gen 3 for sonics and rapid overtaking though. Even my wife says she liked the blue beast better.
