See if I was forced into a darkened room when I was a kid, then tied to a chair and had electrodes clamped to my ears by some assertive market researcher who, while turning the current up higher & higher, asked me if I preferred Dinky or Corgi cars to play with?
I think I'd choose Corgi.
I suppose size-wise you got more car for your money with Dinky but I reckon the quality of finish on a Corgi was just a touch more superior.
Having said that, I sometimes had problems with Corgi's rubber tyres slipping off the wheels when cornering. Dinky, who had a harder rubber compound would tend to stay on when put through similar rigorous tests!
Notice the car from "Joe 90"? Well some of the "celeb" cars I had in my collection in the 60's were - James Bond's (bullet proof screen & ejector seat) - Chitty Chitty Bang Bang (which I hung "flying" from the ceiling) - FAB 1 from Thunderbirds - The Green Hornet limo, and a couple of others.
One I always wanted but never got, was the Batmobile. Possibly the best of the 60's cars, but unfortunately for me, proved too elusive!
