Its two weeks and 300km so far. Here is some updates on the car. Got Vkool 70 done all across including front windscreen. Dent on wallet: 35k. Too early to comment on it as i got this done yesterday. I selected vkool 70 over vkool 40 as the glass is already tinted and i didnt want to darken it further. The installation was very good though. Took around 3 hours and the experience of the installers and the eye to detail was commendable. Vkool dealer was displaying some polymer coating - no brand name mentioned. It appeared to be an extra layer of clear coat. I dont know how good it is or how effective. From his booking sheet i could see that most of the cars which got that done were BMWs. The quote for my car was around 13k. Anyone who has got this on your car, please give me some feedback. Next upgrade: Speakers. I am still scouting for some good ones. On to some annoyances - The front suspension is a bit hard & car tends to go right easily than left. I also have brake squeal. Have to get this checked up. Its either some missing lubrication or some alignment issue.
