Hi Stephen
I dont own one, but was chatting to a Mitsubishi dealer at the Outdoor show at the NEC 2 weeks ago - not sure what spec or engine you're looking at, but apparently the 2.0 litre diesel can be chipped by Mitsubishi which gives it more torque than the 2.2 diesel they have just brought out making it a better tow car if you need more power.
The 2.2 they have just brought out is only available as a top of the range car, so at least this offers more power if required.
Apart from that, it looks like a decent car, unfortunately a bit too small for us. The Citroen C-Crosser and Pug 4007 are built at the same factory, just their versions of it. Cheers Brian
