However, there's this place in Rosemead that does super quality work for a good price. It was suggested on Bimmerforums.com and my friends (who are from Irvine) and I went there. I paid $85 for six windows, the two front A-pillar windows, two main windows, and two rear windows.
The place is called:
California Tint & Alarms Auto
4325 Rosemead Blvd.
I don't really know what to tell you to tell them to get a good price, I just hope they give you a good price like they did for me. I dont' think my friend who did the dealing with them did anything special to get that good of a price.
Maybe try haggling with them.
EDIT: Better yet, ask for Peter, and tell him your friend with a bimmer recommended them.
