How on earth do you know all those cars' names and dates of manufacture? I'm assuming there is a list provided by the organizers. No one could keep all that information in his head! Could he?
Look at how many puzzles Paul has solved. He has more car info in his head than most libraries could ever hope to hold.
I have a little secret: I have an huge index of each manufacturer, tuner, designer, one-off builder and each car made year by year by each one of them.
In my list I have names, cylinders, power, top speed, year, etc etc... and all this in an excel file: if I need to find out the name of an American car, active in 1919, with only 2 6-cyl models, starting with 'S', I'll find out just looking there, using filters and sorting the index.
