I found this on Ebay a while back and I see it's back on there now.It's listed as a Viper S but it's missing one key piece the Ohlins front shocks as you can see from the pics plus unless I'm mistaken they had silver radius rods and trailing arms,not that they couldn't have been painted black it just makes this look like a black Viper with an S hood and seat.
