We had a couple of bippers at work, I don't think we ever got a firm answer, as they were available as a van and a car.


Was the van a car derived van, or was the car a van derived car?


I heard in this instance what would sway it is weather it had a glass back window or not. Ones with a glass back window were car derived, no back window and it was 100% van.


Not sure about weather that bit is true or not though.
