Back in the late 1980's I worked for a private taxi company in New York City. They pioneered the use of the Dodge Caravan as taxis. At the time the Caravan, the first minivan, was only out for a few years.
The owner and Chrysler had struck a deal where he got them dirt cheap, as Chrysler wanted to see if people liked them as taxis, and if they would hold up on NY City streets. They were AWESOME. Customers loved them and they went on average close to 200,000 miles before they were replaced.
Of course, these were 4cylinder jobs with Mitsubishi engines and trannys. A couple of years later Dodge brought out the longer wheelbased Grand Caravan with a Chrysler 6cyl motor and trannny. We tried them and it was a disaster. The engines and trannies failed at a spectacular rate.
