It's a reasonable question-how do I keep track of the "real" mileage"? Well. it’s a little difficult but I do have a method: Ever since the first time I swapped out an odo, I write down the mileage at the time in a folder where I keep most all my receipts, and I'll tell you it's a THICK folder. I write down the mileage of the one that is 'deceased" on the inside cover of the folder, including the date. I also write down the mileage showing on the "new" one.

From there its fairly easy to keep track of the actual mileage. Im pretty close I'm sure, even tho it may take a few days to get the "new" one installed. I'm not out to "trick" anyone about the "real" mileage if and when I should sell the brick. At this point actual mileage is right at 355k-and yes the brick is doing very well. The mileage showing on this latest swap is just over 178k, so I make note, write it down and there you go.

As I said, if and when I were to sell it, the "new" owner will see all this. Ive kept pretty accurate records of "this and that", records of oil changes, tune-ups, tires and repairs along with "tons" of receipts. The previous owner also kept great detailed reciepts. I do keep records of my mileage(mpg) also.
