"Preproduction" car on ebay?

[Ian Stewart <istewart@xxxx>]

Greetings list,

I just got done conducting my semi-weekly sweep of eBay for an 
affordable DeLorean and found this black-painted gem:

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=1826044886

The auction says, and I quote:

Very rare car, preproduction unit chassis #20. Excellent condition. One 
owner since new, former Deloreon Employee. Car is better than production 
units

The exterior photos look exactly like a production car (other than the 
fact that it's black), so is this just embellishment?
