Well you named one of the most important ones and the reason most companies go under, aside from that
You keep your cash, it's tax efficient, you have a nice shiny van every couple of years, you can choose a vehicle you otherwise could not afford and no depreciation. If you add in contract you can have all the repairs and tyre replacements thrown in as well but as new vehicles as so efficient these days I would not bother with even this as they rarely go wrong and only need servicing once a year, plus your road fund and break down cover is thrown in as well.
Other benefits but I think that covers it.
