Memorized the VIN? Yeh, that's fanatical. My dad (also a car guy) once told me that I was going to wax the paint off my Alfa Romeo. Yeh, I'm a little fanatical too. I put my new Norton together in my apartment from the crate and fired it up at two in the morning. Rebuilt a transmission in my kitchen. My 2nd wife was appalled. We are sick puppies.
