Why aren't you putting in your own DIY entries? I do, and my Carfax looks seamless and logical.
Yet another thing that makes Carfax pretty much useless. If you can enter DIY stuff (which BTW I didn't even know you could), then owners could fraudulently enter anything they want.
A few years ago I was looking for a used car and bought ten Carfax reports. Settled on a car before I used up all ten reports and the reports expire, so I ran reports on some of the other cars I had bought new and still owned (so I knew the history) and one car of a family member (that also bought their car new). The carfax reports were glaring wrong for all three.
For one car the report said the car had three owners, mostly likely because it had been registered in three different states (active duty military at the time, we moved a lot), but another of our cars which had also moved with us, and been registered in three states, still showed as only one owner. That second car (my wifes daily) had been in two collisions, minor collisions sure, but repaired at a dealership and paid for by the insurance company both times, neither collison showed up on the carfax report. The family member's car had a very incomplete service /repair history. I do my own maintenance, so of course routine maintenance was missing from my reports, but the family member was a frequent dealership flyer, literally everything besides putting dang gas in the car happend at the dealership, at least 2/3 of the service/ repair history was simply not on the carfax report.
As a result of this personal experience , I put little faith in what carfax has to say (although them not recording the two accidents my wifes car was in may have increased its trade in value, so maybe I should be thankful to them for being inaccurate).
