For what is worth:
I have a 1977 Series III 2.25 diesel, (5 bearings, actually is a LR Santana) with overdrive, it's too slow for modern roads (if I insist for a while I can get it to 90 Km/h or so), it really has a lot of pull and in slow situation I love it, but it's what it is.
Millage is below my 300Tdi, but I would say around 20MPG
Somebody knows if importing a Series diesel is somehow simpler than importing a Defender into the US?
