Harry, back in the late 50's and also in the 60's, model companies such as AMT, SMP, and JoHan offered "annual" kits such as a '58 Chevy, then the '59 Chevy, then the 'Chevy, or Ford, Pontiac, Buick, etc. Just like a real car (1:1) dealership. your local hobby shop offered a new Ford for that year and the new model in the next year to follow. A boys dad could buy a brand new Buick at the dealership every year, and the kid could do the same thing at his local hobby shop. Later on in the mid-60's (?) MPC also jumped on the 'annual" bandwagon and produced some brands of cars in model kit form every year as well. I hope this helps and answers your question.
