Garage cars

I realize that I have probably an extreme edge case here, but I can't put the correct year in for one of my cars. The earliest year is 1950, but my car is a 1923. I was happy to see that I was able to manually enter the make and model and thought the year would follow the same manual input, but was disappointed to see that wasn't the case.

Is there a work around? Right now it's set to 1973, probably because I entered my 1973 first and seems to have just been used for the second car. lol
