With the spreadsheet currently on my PC, I filled out years and trim of cars with the barest of information every now and then when I received a vehicle – rather than being judicious and consistent. As a result, the half-assed spreadsheet on my computer certainly leaves something to be desired. Compounding the issues, I have not been diligent in regards to even marking the windshields of cars with their model year, which would have made this undertaking now a bit easier. Sure, there are a lot of cars I can discern the year or trim just by one look at the front or side – but some had more subtle visual running changes, or none at all. As a result, I will have to jot down the VIN and decode it later for particularly perplexing vehicles.
