I am not always convinced of the new, especially when it comes to reliability either.
I can get 12km/l on the freeway in the 2h carrying a 500kg load, slowly. Even for a modern car, that is not bad. I don't lose oil, no smoke, no kidding. Regular clean oil and fresh injectors.
Same mate has a new prado, it is not much more efficient and too scared to go bush in fear of scratches. It is comfy tho, nicer in the city which is an oxymoron.
The newer vd v8 lc's have awesome power but still drink fuel, I do not think you would get a million k's from one of them, I'd like to know. Let alone servicing electric injectors can be 6x the price than a mechanical injector. And electrical and computer controlled potential nightmares.
I think after what I have learnt and had to start again, I would go the hz. Simple, bit more power, potential million k's and can still get all parts straight from tojo.
