A lot of good ones about now especially the sprinter but for me I would agree with Gerscaff, you can't beat a transit for the simple reason the parts are common and therefore cheap. Which ever you go for make sure it's not all electronic or you are going to have problems.
In my experience everything breaks down at some time or another, even the servicing costs are always a factor when I buy anything. I never really look till maybe the end of year accounts but I would say motor expenses is one of our biggest liabilities.
