2007 Buikc Lacrosse

[remist17]

Well had to get another car and stubled over this 07 Buick. It has 35000 miles and was owned by a old guy that died.
We bought it and general very happy with it. We have some questions for you all.

1- Any thing known to go wrong with these cars?
2- Theres a annoying wishle that comes around 50 mph. Its not a part or beaing grind its a wind noise. has anyone had this before. Comes from the front. Im thinking it either the mirrors or the trim that is in the rain groove that goes front to back over the doors. This trim is a little loose by the front window. Ill try and get photos over the weekend

Any help is appreciated.
