Mcgirr,
I concur with your POWER comment, I had a 3LTR Patrol for a few years and I asked a bit much of her on a few trips and she started getting a bit hot whilst towing so I thought long and hard about a replacment.
I ended up with the 4.5 100 series based on power and price rather than fuel economy . I know others will have a different opinion but for me it was the perfect balance between purchase price ,power and economy.
I get about 25Ltrs per 100km towing my boat but can at the drop of a hat go from 5th @100k/ph to 3rd @145k/ph with boat on to overtake. I love that and find it much safer. (I don't drive at that speed normally ) short bursts of power were what I wanted and the big petrol was right for me .
That said I really wanted a V8 but price dictated the model I got and I was partiall to the "live axle " set up on the 105.
That does not for one minute mean that given the oppourtunitry I won't drive off with your vehical .....LOL
