Some quick searches on car costs and converting between South African rand and USD, it looks like US consumers already pay around 2-3x as much for a car (just in general using averages, didn't look for specific models or EVs).
Car prices in the US are way up over the last few years—prices, which were already trending up, spiked with "Covid shortages" and then just kept going up after those should have been alleviated. Was the ratio as bad in, say, 2015? (I really don't know)
