I have an 87 westfalia that just died its last death!

The VW dealer says it needs a new windshield, new rubber weather
stripping around the pop top, a new radio (maybe just an antenna), some
repair to the dent on the drivers side midpanel, new hoses from radiator
to engine, a new rack and pinion unit, and it really needs a good
detailing inside and out.  Oh, and it needs a new engine, too.  How's
the tranny?  Honestly?  I don't know.

So, with 155,000 California miles on it, and all the above problems,
should I sell it in the paper?  Trade it in for a new "car"?  Or turn it
in to one of the "give us your old car (any condition)" charities?

If I sell it in the paper, what should I ask for it?

Thanks (I'd fix it, but I don't have the skills or knowledge),

Bryan
