I used it to check on my VIN when I bought it (2nd owner)...and there was absolutely nothing on record. I even called my local Toyota dealer buddy and had him check.
I now use it to log every maintenance or service even if I do the work myself. If you have work done at a dealership, it should log automatically to you record...but you have to obviously add the work you do manually.
I also keep a detailed Excel doc on my comp at home where I keep track of absolutely everything I do to my Runner with mileage, cost, & date whether it's a service, part replacement, or simply upgrades I do to the wiring, suspension, goodies, etc...
I'm a bit anal about details :suspicious:
