£390 a month is nearly 5 grand in a year , I know some like the image of a new van etc ,, I have only once bought a new van on a lease , never again . I would rather pay out on my personal car . Cant see the point driving a 15 grand van and a 2 grand car I would rather it be the other way round.
For the 5 grand on a lease for the year , you can buy a van outright for 3 grand ,and have 2 in the bank for in case it goes wrong , it really is a lottery as to whther they break or not. The 3 grand van will always last 3-4 years , by which time you are well ahead vs the cost of a lease.
But for knowing where you are with outgoings a lease/hp is best , unless you get hit with damage fees when you return it, or have a downturn in work ,and struggle to keep up the payments.
