Dont forget though, brand new does not equal reliability. We have some Ford focuses (Foci' ?) at work. None are any more than a year old and the worst out of the bunch has had the AA out to it 15 times so far. My 2.5 year old car has been in the garage more times than i care to remember. Admittedly, we do use them more than your average school run mum but the point still stands that new does not equal reliable.
If it were me, i would be going for a end of lease vehicle direct from the auctions but find out who the lease company was. Some really look after their cars, others will just have the minimum done to keep them road worthy before they sell them on. Alphabet for example, I've heard stories they won't even pay to have their cars serviced at the recommended intervals and even when they do its by Halfords auto centres. I would trust my dog to do a better job at servicing a vehicle than them idiots.
