Of course it is possible that they are beautifully maintained and drive as they should. (As a comparison, none of our CAT C vehicles has exceeded 100,000 kms. Most have done no more than 30,000 kms. They drive as they should).
I’ll lay money the trucks pictured are manual - probably range change. As said, if they drive properly, apart from being an added hurdle, it might not be an issue.
It is a fact that it will take longer to master a manual than auto. It’s another fact that folks fail on “use of gears” from time to time. Cant happen with auto. The rules changed to allow auto in 2014. (For interest, the first batch of auto trucks purchased new in 2014 are no longer on fleet.)
Make sure you check out reversing facilities. I wont mention instructor qualifications - even less training centre accreditation.
Not all training is the same. You pay your money, you take your choice.
