(ET) electrak dollar value?

[Oasis654 aol com]

hi folks, i recently acquired 3 near virgin electraks - stored in barn for 
30 
years with no batteries in them.  i'm going to keep one, sell one, and 
donate 
one to a local college where i hope it will be used as an educational tool 
for students interested in electric vehicles.  
    the college wants a value placed on the gift and suggests that this 
value 
be estimated by someone familiar with the equipment. hence my request to 
the 
list.  
its an e8 that appears to be straight from the showroom, complete with 
deck 
and new batteries.  would someone with knowledge in this area give me 
their 
best guess as to the value of this machine.  thanks for your help, jon k
