Mort,
I have no experience myself, but I have a lot of clients who do. 😀
I was speaking to one this morning, she is responsible for a fleet in excess of 1,000 vans of this size, so I put your question. In her experience, in order of overall value, which includes purchase/lease costs, total cost of ownership, reliability/down-time etc she ranks them…
1. Berlingo/Partner
2. Combo
3. Kangoo
4. Caddy
She made the point that the equation can often be skewed by any special deals that may be available from manufacturers at any given time but, if you are buying used, then this probably won’t affect you except insofar as the ones that give her the highest residual values are the ones that are going to cost you more to buy.
