I love the 'old' shape also and had one.
The newer shape however if you look at the width of the wheel base it is much the same, but the 'body width' inside is
somewhat smaller because of the 'round' edges.
There are some good buys out there, if you are going to do 'lots of mud & sand & dunes I suggest manual petrol.
Autos are great & many of the 'Trollie' oaks will confirm, I just like the choices of my revs and my gears!
Also tyre type and size!
Will gladly talk some more!
