Here's a screen shot sample.
Column 1 is the date acquired, vs. dates produced in Col. 7. Description in Col. 8 can get lengthy - for some cars, like French classics, I list the chassis number, how it did at Pebble Beach, etc. so I don't wrap the text. Hence, the test file wavered into Cols. 9 and 10, which I left blank here. Col. 11 is the vehicle type (SPT=sports car, WOD for woody, 500 for Indy, etc.) so I can see how many of a particular type of vehicle I have. I color shade this column to reflect cars I've seen, or earmark future disbursements to my kids. I also use Col. 13 to list who I bought the car from, if I can remember.
