Well... Unfortunately, aap ka experience theek nai raha. I have taken their services twice in Islamabad, and am completely satisfied. May be, some things vary from person to person, or city to city, but overall, SOPs, Quality of service, professionalism must be the same.
I have just checked, here is the link to one of the latest reports: https://www.pakwheels.com/carsure-reports/312860 ( through the link: https://www.pakwheels.com/products/pakwheels-inspection )
The overall score is based on 10 (pehlay aesa nai tha, it was based on 100), whereas other parameters are based in percentages (100 scale).
Now, that's something strange. With my 02 times experience, they did not ask me to drive the car, instead, they drove the car themselves, and I also insisted them to drive themselves. Agar main drive karoon ga, to team ko issues ka kaisay pata chall sakay ga?
Well, I think, it can be a possibility. Jo banda denting daikh sakta hai, wo paint work b daikh sakta hai, and it's not very difficult. Similarly, a mechanic can also look for some electrical things. They are just inspection team, they are not repair guys, jo agar issue aye to masla hall kar k dein. Unka kaam just inspect kar k btana hai. AC chall raha hai, theek hai, Tick ka Nishaan, nai chall raha, cross ka nishan. Ub kyun nai chall raha, iss k liay, I think, relevant persons are there in markets. (Main innki waqalat nai kar raha, just sharing my point of view. Others can totally disagree).
I have a bad habit, main bohat zyada sawaal jawab karta hoon'
(mainay dono baar teams ka acha khaasa sir khaya tha, since I believe, jub takk aap puchein gey nai, aap seekhein gey nai!) Agar koi minor issues they, dono baar teams mujhay btaa k gye thein.
If you are not satisfied with the team, you can first directly contact them, if you have their contact nos. Otherwise, still, you can call on Pakwheels Contact No. and show your concern.
And I totally agree with all of your 03 last proposals!
