Me: "Yeah, I need a couple of parts, and I have the parts numbers." 
BMW Classic Certified Parts Guy: "Why don't you let me check those part numbers.  Let me have the last seven of your VIN."
Me: "You are not going to find my car that way, can't we just use the part numbers?"
Parts Guy: "I want to make sure they will fit your car.  Let's try the last seven of your VIN." 
Me: "The VIN for my car only has 7 digits." 
Parts Guy: "Well, all cars have 17 digit VINs. So, just given me the last 7 of yours"
Me: "Actually 17 digit VINs were adopted in 1981. My car is older than that."
Parts Guy: "Ok, so give me the last 7 of your VIN."
Me: "If you insist -- 2250002."
Parts Guy: "Yeah, so neither of those parts will fit a Euro e21 323i." 
Me: "I don't own a Euro e21 323i." 
Parts Guy: "But your VIN says..."
And so it goes.  Oh, and this was the BMW Certified Classified location for the Washington, DC area.
