Hi John, I know this is a bit late, but I can provide a bit of insight into the 300tdi. If you are looking for north american power, the 300tdi is going to leave you underwhelmed. It is miles better than the 2.5td both for power and reliability, but keep in mind its only about 120 hp stock. I’ve got a 110 with a 300tdi and it works well for me, but I have the 1.6 military transfer case with an overdrive so kind of get the best of both worlds. I can do 65 MPH without too much strain and don’t have to slow down too much on hills. What I do like about the combo is it is very efficient. I get 26-28 MPG. Not bad for the aerodynamics of a brick.
