Exactly this is what i am experiencing. I feel a resonance running through the car's body and i can feel it in the steering wheel, the floor and the seats.
To put it in layman term ( gaari me gooonj mehsoos hoti hai 2.5k to 3k rpms ).
when i showed it to my brother his words were and i quote " ye to aise goonj rahe hai jese 125 ko full race di ho ."
i will be visiting toyota on monday and if this thing is built in corollas then my car will be on sale by the evening.
highly disappointed right now.
