I don't really understand - by what method are they labelling cars 'medium' or 'large'?
The Toyota Camry was a medium car in 1992. But in 2012, it's by all methodology of testing, a large car. It is as long and as wide as an EA-ED falcon.
Belive it or not, my current model corolla:
is as big as an SV21 camry!!!:
