Cooool!
I bet if you drove such a car to your service calls your customers would be quite impressed! [Linked Image]

Here about every contractor had a Volkswagen van back then. In the 1970ies Toyota LiteAce started to come up. When I was a kid in the 80ies and early 90ies about every plumber, sparky,... drove at least one white or yellow LiteAce. Some of them (or hould I say surprisingly many) are still around.
