Thanks Smartbomb
I did get a tank full of fuel with the car, so they haven't short changed me on that (I probably made a little on the deal in fact).
Very happy with the service received from Sytners, they even rang me today to check that the car was OK and I was happy with everything (already done 400 miles in six days- with no problems).
I could ask them about the fuel charge, but I don't need the hassle. We're just enjoying owning the best car on the road (Cool and mellow!)
