my first discovery(the one in the avitar)was a v8,cracking motor a real joy to drive,would have pulled a house down,she did hate water though despite my atempts to sort that out.Just one word to the wise though mate they are not cheap to keep fueled up your going to get around 18mpg towing caravans,some truely frightening mpg figures around town and stop start driving and at best 23mpg on long runs.in the end she had to go.as said try and get a lpg converted one if you dead set on a petrol but i replaced her with a diesel it doesnt sound as nice granted but that roar of the v8 soon wears off.also its going to cost you more in service items,plugs,leads,dizzy cap,etc.hope this helps mate,the figures i have quoted are not set in stone some will get better mpg but some worse.hope you find what your looking for.
