I would dearly love to have 1:43 models of both. My first car was a six-year old '61 Valiant, but'62-'63 Corvair, preferably turbocharged.
There are several 1:43 '60 Valiants on e-bay now, all out of Australia, for prices up to $260 dollars. And shipping from Australia is pricey in my experience. I don't want it that much!
Yat-Ming makes a 1:43 '69 Corvair convertible - Amazon has tons of themfor $6 to $9 depending on actual supplier, and Brooklin makes a 67 coupe you can get from DiecastDirect right now for only about 12 times as much!. No one seems to make a model of the first series Corvairs though (as in '60).
