What would really help would be if we had a data base
of sales prices and of what ins. companies have paid
for totals. 

Two dealers that come to mind are:

J&R VW Vans / Keystone Auto in Reno, NV
Hoch Motors in Santa Rosa, CA 

Maybe they could help out with sales documentation.  Jerry (J&R) seems to get top dollar for his vans.  I own one and he didn't budge on the price knowing what a clean Westy Syncro is worth.
