If your transit is in good condition, has been serviced well and generally doesn't give you much trouble I would keep it. It should be good for 150-170k and you'll be payment free from next year. If not then I would sell it, put a bit of effort into buying a good second hand van, private with NO vat for around 4.5-5k outright. It's a business tool, an expense at the end of the day- depends on your personal situation I suppose, all I would say is don't be too eager to hand over more of your income to someone else than you need to- all that counts is how much of your turnover YOU get to keep when the sun goes down!! The easiest thing in the world is to spend someone else's money!
