My ’98 WS-6 Convertible was noticed on the truck in May of 1998 as it was being delivered to Dearborn Pontiac in Dearborn Michigan. I happened to be out of town and my wife was getting our ’96 Grand Am serviced. She inquired about the car because it looked very unique to her. To make a long story short, she put a down payment and I completed the transaction once I came home and saw and drove it!
I have managed to do some research into it because I know the SLP/ASC did not do convertibles until later in the year. So here are some of the facts on its exclusivity:
Of the 3083 WS-6s built in 1998 360 were convertibles of which 86 were Red (confirmed through ASC). Only 18 of the red convertibles were made with the Taupe top and interior (most were Black).
Also, as you will recall, the SLP dual-dual exhaust system was available on the Camaro SS but to get it on a Firebird you had to order a Firehawk. That was the way SLP decided to make it exclusive. So as far as I know and can tell, I have the only Red ’98 WS-6 Taupe Convertible with the dealer installed dual-dual Firehawk exhaust.
