In the end, a third of the Mexicos sold were equipped during the production cycle. Top speed increased from 240 km/h in the 4.2-litre version to 255 km/h in the 4.7-litre version. Other minor tweaks were made to the model in 1970, including alloy wheels in place of spoked rims. However, these were still available in Bolt-on version, but no longer with Knock-off system. A total of 480 Mexicos were sold in seven years, including to Italian actress Virna Lisi, American actor Ronald Reagan and middleweight boxing champion Nino Benvenuti.
