Hi all, I\'m looking to buy a 2007 Subaru Legacy 2.5L manual wag. I did the drive test, all feel good but the only thing I am concerned about the 5-speed gear box. The gear box itself has no problem (I hope), it shift gear smoothly. But when I put my hand on the gear knob, it seem to be excessive movement/shaking of the gear stick under normal operating condition. My questions are: Is that normal for manual Subaru? Is there any other common problem of this particular model?
