1 - buy outright
If you want a brand new van, then this is the most expensive option as a new van could set you back over £20,000 (or more).
But on the plus-side, it gives you the most flexibility. It’s your van, you can do with it as you please – sign write it, paint it, stick alloy wheels on it – whatever!
On the downside, if you have any problems, you have to pay for all repairs and maintenance.
