^^ lets take the same Prius as taxi and replace the city with Karachi.
In NYC
HSD calls for workshop visit in car
car gets decommissioned and towed/driven to dealership
dealership repairs the car in given book time and delivers the car back in proper work order - usually less than 1 day for small jobs (it is expected the cars follow proper preventive schedule too)
Parts replaced under warranty (if applicable) readily available and labour workmanship is also warranted.
Car back into 100% spec service
In Khi
HSD calls for workshop visit in car
car gets decommissioned and towed/driven to dealership
dealership refuses to work on HSD
In an ideal situation - read below
HSD calls for workshop visit in car
car gets decommissioned and towed/driven to dealership
dealership refuses to work on HSD
car gets towed/driven to private workshop - where it gets opened up and parts list is generated for repair (still a pipe dream though)
parts availability and cost is argued upon as its extra-ordinarily high.
parts ordered and delivered in about 2 business weeks (also add shipping/customs charges)
private workshop takes no responsibility of any repairs done to car.
car cannot be certified/signed off into 100% spec service condition.
