Thank you for the feedback!
Well, regarding fuel economy it will guzzle about 1.7 liters of 98 oktane fuel per 10 km, with just the rear, two wheel drive engaged, and no off roading.
Part of this is off course the old scool 3l petrol engine, with a pair of pretty inefficient carburettors, and the less than ideal aerodynamic design.
With four wheel drive and some serious terrain negotiating, it really makes no sense to even contemplate such matters...
Regarding the Pinzgauer design similarities, I don't really know, but the true ancestor of the Tgb 11 is the Volvo 903 Laplander, aka Valpen (the puppy), which was designed in the early fifties. But I agree that the simularities are striking, and probably so for a reason.
Good news for you then Tee Dee, I hear that when the Swedish armed forces sold off a bunch of theirs, quite a few of the better examples ended up in the UK, bought by some vehicle surplus company, do a search and you will probably find one, but beware of the rust though, some ex military individuals were given a second life with zinked rust protection, go for one of these.
I know my english is far from perfect so if something is unclear just ask again.
