Many years ago in Adelaide, South Australia there was a newly opened Freeway. Driving on that freeway fairly frequently there was a large, V8 Jaguar with a turbo fitted to it's engine. No local police car could catch it. There were frequent grumblings from the local police that the naturally aspirated V8s from Holden were, in a word, "useless" when this thing came burbling past at 180 km/h (maximum state speed limit was 110 Km/h).
Mistibushi heard of this. They were working on fitting a turbocharger to their Starion sports sedan. They went to the SA Police and asked if they'd like to test the turbocharged version of their Sigma Sedan. "Yes, please!" Answered the Police and so plans were laid to trap the Jaguar, "in the act". So, early one day, they set up their trap. Along came the Jaguar, chase was given by the patrol car, a normally aspirated Holden V8. The driver gave all he could but he couldn't catch the Jaguar. Suddenly from an on ramp came the normal, naturally coloured (all Police cars were a powder blue in those days) Sigma. The Jaguar slowed down a little but the Sigma speeded up. So the Jaguar sped up. The Sigma passed the Jaguar at 190 km/h. The fully uniformed Police officers flagged him down and pulled in front of him. He slowed to a halt and was found to be a middle-aged Doctor who was laughing in his driver's seat. He knew his days of speeding were over. The Coppers all apparently had smiles on their faces as well, they knew they'd caught the bugger.
