From its Victorian taxicab yellow to its limited run (only 85 models were ever produced), the GTSR is an HSV oddity. This GTSR is really a mockup of a race car that never existed, but where it fails in legitimate racing heritage it makes up for in glam. The specially-built V8 under the hood makes freight train-like power from idle to redline. This is one Aussie rarity that you may not have known how much you would appreciate until you get behind the wheel. In other words, hop in and hang on.
