Wow I totally missed this thread I can’t believe it.
Inherently, I don’t think an HD 70 from the same period should be worth any more or less than a KZJ7x, depending of course on condition.
I own a KZJ71 and I’ve driven an HZJ78 in Uganda. I definitely appreciated the robustness of the 1HZ out in the bush, but once on a highway trying to maintain speed up a hill, I instantly thought of my 1KZ back home. It accelerates better and is just more fun to drive than the heavy HZ car in my opinion.
My KZJ71 is so good at everything I need it for. Long road trips, parking in the city where I live, and it’s seriously wonderful off-road, especially with front and rear lockers. I’m not going to carry a huge payload in it, and that’s fine, it’s not what I need it for. The 1KZ is an awesome engine. I’ve seen many with 400,000 kms still going strong. The body panels are the same as an HD 70 and so is the frame.
I won’t even address the HDJ81, they just aren’t as cool as 70s. Only joking of course.
