Hi all

I am wanting to buy a 2001-2003 area Pajero Exceed and currently in the research stage. I have driven a petrol model quite a lot but what I'm wondering is should I go petrol or Diesel?
I'm looking at doing 50/50 city / off road use.

Two factors mainly:
Which is better value for money on fuel usage?
Are there any reliability comparisons I should factor in?
