IMO the ad is misleading because:

1) it never says they AREN'T "NOS" or that they ARE repros
2)the bidder's ID was kept private, which is pretty common for collector cars or parts vs the more common show everyone in your "run of the mill" repro parts auctions
3) he makes an effort to describe their application and part numbers and dates in detail, BUT leaves out they are new manufactured
4) he shows close ups of the dates and part numbers which is more commonly done with an item of collector value as the value is likely in the "details"
5)he mentions his business and the fact they have been doing it for 20 years, serving the public and implying the collector in the process
6) he uses words that are "attractors" in his title.."Yenko, COPO and Z28" vs. just saying these are "1969 Camaro spiral shocks"..he obviously wants the guy looking to restore a car correctly vs. the guy wanting a shock for an old Camaro
7) most importantly he says "bid with confidence" which implies he is fully disclosing..at least to me

Again based on his ad and his resulting emais...not the guy I want to do business with as I'm not an "expert" and there has to be a certain level of trust when buying these types of parts or cars. Hopefully he will make the situation right...just my opinions and observatiosn.

Repsectfully,
