Seriously, most businesses at one time tended to buy vans outright (or finance them) and lease the cars, although the likes of Northgate are changing that perception. Leasing a van is becoming more popular as it requires less initial outlay to get a vehicle on the road.
Being LTD and VAT registered could probably mean you have a couple of employees, although not necessarily. Vans were treated as an asset on the books, generally due to the nature of the way that staff treat them. This was especially true in the building industry where a finance house wouldn't consider a contract hire agreement with vans to them.
What you have to consider is what you want at the tail end of the agreement. It's great having a lease with a large balloon payment at the end as this reduces your monthly rental, but what happens if the van, for whatever reason, doesn't fetch the value is was expected to 3 or 4 years previously when the agreement was drawn up? This can put you under a lot of pressure financially. What about over mileage charges? What about the cost of making right that 'non wear and tear' damage, dents, bumps, scratches, etc. (If anyone does choose to lease a van, get a copy of what their 'wear and tear' conditions are, read them and understand them before you sign anything.)
Some people loved the thought of a low monthly repayment, but then they started to have second thoughts as they were now handing a vehicle back with value that they had paid for every month with now nothing to show for it.
Leasing is about financing a depreciating asset. Whichever way you choose to finance a new van, once purchased it will always depreciate and you will be left with something of much less value at the end of the day.
Each finance deal has its pros and cons. You need to identify what to you are pros and what to you are cons. I might have a totally different opinion to you on the same deal.
