Update: I and Parantap did manage to pick ourselves up early on Saturday morning and took the long and arduous journey to Kashyap Noida. Unfortunately, neither Mr Sharma nor Rafiq (his right hand man when it comes to diagnosis) were available for different personal reasons. I left the car with them since I had to attend an official engagement in Noida. Came back around 3 pm and found that all they had done was swap the right sided tyres to left and vice versa after balancing them again (they did that two weeks ago as well). Car was out for a TD at that time and once it returned, I was told that the vibrations are not there now. I knew nothing much would happen today since the main protagonists were not available, so decided to get the job card closed and leave. Forgot to mention, the Jet had been rear ended by an Alto last week which resulted in a slight misalignment of the rear bumper, which was also fixed while I was away. The stupid Alto was left with a damaged bonnet and dislodged front bumper as a result, while the mighty Jet made it with a minor repair job (misaligned rear bumper, partly broken chrome strip on one side - pasted back using some feviquick for now, and some minor scratches) - Thank you Fiat!! I did find that the vibrations had reduced substantially (well maybe I am nitpicking when I say that). Will drive around a little more before I comment back.
