I don't know the phone number of any runners, but when I sold my car, the buyer wanted to do a mobile inspection instead of an inspection at the
puspakom headquarters. He was willing to pay for it, ($140) so I agreed.
The buyer claimed that the mobile inspection guys were more lenient and could be "reasoned" with, if the inspection failed due tinting.
The inspection could also be done in the bright sunlight, (up to you to park your car in the sun, it's a mobile inspection team, they will come to wherever your car is parked)
which some claim increase the chances of passing the tinting test.
However, the inspection passed, and there was no "reasoning" required on the buyers part.
So all of his theories remain untested.
If you so desire, you may book the mobile inspection team through the puspakom telephone number.
I believe some lead time is required, they call to set up an appointment.
All the best with your inspection.
Sorry was unable to help with the runner phone number.
