Because of my stupidity. I made a big scratch on the driver, passenger & back windows. Its so unpleasant to the point that i really need to change it. I already made an evaluation from my insurance that may cost me almost $800 overall. They will only cover me for $500 & ill pay the rest of it. My problem is... i called these auto window replacement services & their estimates are gonna costs me $1300 in total. I called like 5 different services & their prices a constantly at that 1.3k range. Is it cheaper if i'll just buy the windows/parts online & find a shop to install it?
If yes, where can I find a decently priced & trusted online vendor on these parts. Help please.
