I would recommend the Transit Custom SWB, great vans but they’re going for stupid money in the second hand market at the moment.
If you’re buying nearly new/used and taking finance, beware of inflated interest rates, garages will try to sell you HP at upwards of 8%, much cheaper way would be to get a personal loan which can be had for under 3% depending on your financial situation.
Buying new, Ford offer 0% finance with a 30% deposit, just make sure if you do go down this route that the dealership is still applying a generous discount (Ford discount as well as a dealership discount) It may be worth asking what would be their best price for buying outright and buying with 0% interest.
