As long as its had a good sevice history , there should be nothing to be worried about , that sort of mileage on that age of car , would be mostly motorway i would imagine.
39,000 miles for a 2 year old diesel is nawt! thats average mileage, if it was a petrol with 40,000 miles then it would be high
i bought my 08 smax with 100k on the clock,full history.
ive had it now approx 14 mths and its now got 107k.
i phoned the ford dealer about the car and they rattled off what had been done etc
i kindly asked for a print out and the guy said i was having a laugh as it would need a tree to print it all,lol
mine was in every few weeks being serviced etc.
Welcome to the Forum Craig.
That kind of mileage on an ex fleet car is nothing to worry about, it's probably all motorway mileage and no problem at all.
I have an ex fleet 07 Focus that I bought with 70k on the clock and it was mint and runs like a dream.
I'm happy you're happy. :)
Best of luck with your new car mate, and don't forget the photos.
