250gd..I can't speak to it because I haven't driven one. But I am guessing that's the wolf model. It's a fair bit lighter than the 5 door LWB. While the OM606 develops 175hp and 330Nm of twist..the 250GD (if my research memory serves me right) produces 90 odd hp and I think 140Nm of twist. It developed a fair more in the 290GD form

Now if you think about adding 33" tires, overlanding weight etc, you are looking at a very very slow highway cruise..I would think 60-65mph. But the 602 is a bullet proof engine and if importing it wasn't a hassle I would have gotten a 290GD 461.
My 463 is chipped so it puts out a bit more at the expense of getting 15-16mpg but it cruises at 75 mph with plenty of power to pass with 4 passengers and luggage.
Sorry for the long winded response but horses for courses. Do a but more research at clubgwagen.com as well. Lots of good info there from veterans.
Good luck with the search..
