On the British motoring show Top Gear, Richard Hammond drove a 1963 Kadett A through the middle of Botswana and across the Makgadikgadi Salt Pan. He loved the car so much that he named it Oliver and later had the car shipped to the United Kingdom and restored, and it remains in his possession. It appeared on Richard Hammond's Blast Lab with the personalised number plate 'OL1 V3R'. It also appeared in the Top Gear lorry challenge as one of the used obstacles.
The GSi's engine mapping had been carried out by Opel tuning specialists Irmscher. A model with the 82 PS (60 kW) 1.4 L multi point fuel injected engine, which was otherwise mechanically identical to the GSi, also became available as the Nova SRi in the United Kingdom. In January 1988, a turbocharged version of the Isuzu diesel engine was introduced, with power increased to 67 PS (49 kW).
