I had an '81 for a while. I didn't like the fact that you are stuck with the lightweight wheels unless you relace some standard rims to the hubs. Mine was in impeccable original condition so I didn't want to go that route. I got it as a trade for my monster trike (see intro). When I got the T&C it had a 600w hub motor on the front, but came with the original parts as well. After the novelty of the trike wore off I sent it down the road. I kept the hub motor set up and cleaned it up. I couldn't get the $300 I was asking for it, but I did get $125 cash and a Giant hybrid bike for my wife for it.
I usually see them for sale in the $300 range if they are in good condition.
Short version: Fun to have, but you can fit 3 regular bikes in the same room it takes to park the trike.
