These Dodge vans are also legendary and it is possible that all the things said above are true, however it is also possible that all this van needs is a good clean some fiberglass polish, fresh fuel and a few miles under its belt and could give you many miles of joy. It looks like a BC plate on there so if that is the case and it has been sitting under a tree for a couple a winters in North Vancouver it will look pretty ugly in no time. If you have no mechanical skills this may not be the bargain it looks like. Other things that may be shot are brake lines, fuel lines, seized brake calipers, however if it starts, all the lights work, drives down the road, brakes work even if they are a little squeaky at first it may be a fine purchase especially if you intend on using it in one area for awhile before heading off on a long remote trip in order to get the niggles out and gain confidence in it. These vans have a history of reliability, I had one in the mid eighties and it never let me down, I drove it to Alaska a couple of times. As said you will likely need to spend some money on it but that is true of most vehicles under 8,000. If mileage is very high I would leave it personally but if mileage is lowish 120,000miles or less I would have a closer look and a test drive, bring a friend that is mechanically savy along, shout him or her lunch.
I just read the Craig list add, it is BC , I would not be afraid of this van based on the add, the roof can be made to look like new with a bit of fiberglass product from your local boat shop. the only reason I would not buy it, is if it was formally an out of province van but if it lived on the Island or in the lower mainland all it's life I would not hesitate I it starts doesn't smoke and runs well, It has not been sitting very long.
someone with some mechanical skills, and maintenance knowledge once owned this van, it has extra gauges, looks like oil pressure and a voltmeter, as well as a tachometer. Someone took care of this vehicle in the past, iikely the guy that owned it for 20 years so regular servicing will most likely have been done. Another plus.
