I'm not too sure about th 4x4's you've driven Mith but on the ones I've driven (even the old ones) the gears engaged positively and smoothly. If they dont slide into gear nicely then I'd be curious as to why... Finding the gear, you would expect it would take you a while to learn where they are, but fighting to get into gear, I'd be concerned.
Dont expect the 2.5 to set any lap speed records! But it will pull a heavy trailer for you. Geared to work not race!
The closest I came to buying a landie was about 3 years ago. I was seriously looking at a 1963 80" series II with canvas top, 2.25 petrol engine, pto winch and a bunch of spare parts. Needed a lot of work but was a worthy classic. I just couldnt pull the trigger and eventually it was sold to another. I really kicked myself for dragging my heals on the purchase. The asking price of that series II was £550 sterling.
Following that, I worked over in Cambridgeshire, UK for 8-9 months having changed jobs. I figured I'd easily pick up another landie while there, scanning every auto trader and local car mag trying to find one similar but had no luck and came home empty handed.
Moral of the story, if you want it, and it looks like a good deal, and you have the spare £££'s, then buy it!
Just make sure it is mechanically sound.
Heres a photo of a series II similar to the one I wanted, I have this photo as a screen saver on my laptop to serve as a permanent reminder of how stoopid I am. A polished aluminium landie (this is NOT the one I was looking at!
)
