thank you rahaansaed.
My plan is to save as much as i can without compromising on quality:). reason last week my front wind screen was broken as it was exposed to direct sun all day and i did not crak my windows to cross air.
as you can see from the pics damage is not much. it is a very small upper glass that broke. luckily inside glass is safe and indicator is also covered with another layer of glass. so dust wont make any difference to its quality. i guess i will have that piece fix easily.
