Dont get a D3 or D4, terrible reliability and massivly expensive when they go wrong (EGR valves are a very common fault and pricey). Jap stuff is so much better than LR unless your getting into serious off road stuff then the LR starts to make sense...
Nothing wrong with the D3 / D4's if you're happy to do minor bits of playing with them. They look a lot better than that jap **** stuff too.
