Hey guys, New to the subarus, Ive been very interested in a used 2007 Legacy limited. Its a 1 owner car with 174900 miles. BUT you couldn't tell by looking at it. Very clean inside and out. What are some things I need to pay close attention to on this future purchase. I did drive it today, the only thing I noticed is when you turn the wheel either direction I have some sort of vibration coming from the front end. Now I know in most 4X4 not AWD...when its engaged the front wheels will not turn all the way with out giving you some noise. Is this common in the subarus? due to the awe? I have no interest in modding the car yet, just wanna get in and drive. What should I be on the look out for?? THanks,
