As a 2m tall person, the topic of cars for people of my height comes up on occasion. I drive a 1998 Volvo wagon, but have been successful driving cars as small as a Fiat Uno and a Ford Ka (in Europe and Argentina respectively). And been totally unable to drive a Ford Tempo (sun visor blocking forward view) and had a lot of trouble with a Honda Civic (1st and 2nd gear being inside of my right leg). I'll probably add a bit to this later, but there is some dimensional information available at Edmunds and elsewhere.
Notable used cars would include Saabs, Volvos, BMWs, and Mercedes in general, and the VW Passat, Toyota Avalon & Cressida (going way back), Nissan Maxima, and Mitsubishi Diamante.
