This story is real; at least in the sense that the originator is a party to the episode.
About ten years ago, I wanted to buy a new car and while doing an internet survey of models, price, performance and complaints, came across harpreet's letters to his dealer.
This is what Harpreeet had to say about his Ford car.
The car AC was over active and he was shivering and freezing while driving. He complained to the dealer and told him to fit a thermostat or take the car back. The dealer (same jati) advised him to keep the window open, which was rejected by harpreet as the manual said to keep the windows up. And the wise dealer advised him to keep both the ac and the heater on. Harpreet wanted to know how to do this.
Second complaint: Harpreet's car was white. Its top was turning yellow. The dealer suggested a fiberglass/chemical coat to protect the paint. This was done; but the yellowing continued. The second exchange of letters between and harpreet and the dealer on over-painting, stripping fiberglass and repainting, sharing of costs were hilarious.
Even today mere mention of 'harpreet' makes us burst into a loud laugh even when we are in a sullen mood.
