Your 2005 Buick has Front Wheel Drive, and as a result the engine connects to the transmission under the hood, adjacent to the left (?) front wheel, not underneath the center console. It is entirely possible that you have one or more bad motor mounts or transmission mounts, so I think that you need to seek yet another mechanic.
