I loved the Legacy GT wagon, and should my beloved E46 meet an untimely demise I would be at the Subaru dealership tomorrow.
I don't drive nearly as agressively as some here, but I found the LGT a hoot to drive. The ride wasn't as firm and controled as my SP equipped car, but it was plenty stiff enough to be VERY entertaining.
I was only able to drive an auto, but ran it in "manual" mode the whole test drive. The tranny was very responsive and shifted quickly. I found it very easy to drive for long periods of time in this mode as apposed to a BMW Step which I found downright furstrating.
