hello there.My husband is now in LA for a month long business meeting. He has this IS250 but the problem is now he's been hearing some rattling noise on the rear window/parcel shelf area. The mechanic that I just phoned up here in NY told me that he needs to replace the whole rear window. Gladly I saw this Los Angeles Auto Parts which is based in LA. I want my husband to personally get it from there or deal with them perhaps but he's too busy so now, I'd like to know if ever he'll get the parts from them, would he not experience any trouble?thanks and am so sorry if I have to do this and not my husband. he could have explained it better.
