Well, if you are planning to rob a bank, and use one of these as a getaway vehicle than less,as these were mostly used for this purpose in the 1970s but am told that the engines in Fords are unreliable. Have only ever had one of these in our family, and it cost us more to get it fixed than it did to buy. Some people I know will only ever buy Mercedes Benz Sprinters, but think they cost more than Trannies. Also Trannies tend to rust quite badly, but that was on the old models, perhaps the new ones are better.
Not really sure what advice to give you, but my experience of them has not been good.
