I sometimes wonder about the condition of cars in the twin cities - I spent a whole day searching both cities for coppaslip - in the end, after dozens of shops, one shopkeeper managed to find 6 sachets (one is enough for brakes on one side) leftover in a worn out carton.
That means that almost no car in these two cities have 100% effective, silent, factory-spec brakes.
Same story with CV Joint Grease - even the liquimoly distributors here were out of stock - they had to have it ordered on request.
Wheel bearing grease proved almost impossible to find - I tried calling Shell on their helpline system to inquire about Gaddus - their helpline system was absolutely useless.
in the end, I managed to find some khayp, UK branded NLG-2 grease that didn't have a TDS on their shady website. Genereic NLG3 grease is the norm here.
The commonly held belief of "Used cars in Islamabad are in excellent condition, hence their high asking price", is probably a myth.
