LDV’s are very cheap and reliability is ok as they use old ford running gear (unless you’re talking about newer maxus vans, not so sure on these) but they are horrid to drive. Uncomfy, slow and just not a nice place to be. I wouldn’t want to drive a long way in one regularly.
Iveco daily’s are ok vans, used by lots of couriers etc. Rear diffs are expensive when they go and gearboxes are known to be less than ideal. The engines seem fairly solid but aren’t the most frugal.
How much load capacity do you need (in terms of space and weight) and what’s your budget?
