Fair points.
I personally wouldn't have paid for the install as £2000 goes a long way in petrol.
I do a low 4-5k a year so wouldn't have been a viable purchase, in a way of recouping my investment.
Not being mechanically minded, didn't know it could damage the valve seats!!!!
My car has only done 87k but, from what I have been told (and I have no reason to doubt) it was once owned by Prins, who used this as a demo car.
I do use petrol frequently as there is no LPG Garage nearby so have no option unless I want to travel around 30 mile round trip, which sort of defeats the object.
I have the doughnut tank slung under floor where the spare wheel fits so no loss of space or ugly install.
We are moving on Thursday and there is a Flogas depot around two miles away and there LPG is 0.52p per litre, so would be a considerable saving on petrol.
Thanks for your reply.
