Searching for a GN: what does "Exceeds mechanical limits" mean on a vehicle history report??

[LomoMike]

Hey guys, need some help with this one. Looking at a GN in a few weeks in PA. Ran the vehicle history report and it got a low score on Autocheck because of something reading "exceeds mechanical limits" on the report. Im assuming this means that the odometer has rolled over past 99,999 miles. Ive attached a pic of a section of the report. Take a look. Correct me if i am wrong but this car would really have at least 240,000 miles on it??

Car looks to be in great shape and engine and trans rebuilt. Guy is asking $13k. Need to know if its worth it before i make the trip from NY.
If this post isn't in the right place feel free to move it.

Means that the clock stopped counting at 100K miles and you are now on the 2nd, or 3rd lifespan (100K miles)

A GN with 140,000 is not worth 13k...so save the trip

once you replace everything that can wear out, and upgrade a few things just because you can, mileage no longer matters. and in the case of the suspension and body mounts, it's probably more solid than it was when it left the factory.

Metal fatigue is metal fatigue. I would not even consider having anything even close to 100K other than my body. I am 71 and I can only imagine how a car is after 100K.
Yes, it can be done. Better to go the opposite way and buy extreme low mileage anything.
