they are ok, not that bad, you just need to get use to it.
its 300 to 400 kgs more weight, i remember they feel much heavier in cornering and braking but acceleratoon wasnt too bad.
great in high speed cruising, well planted and heaps of grip, but not as good in tight slower corners.
rear seats arent that useful either :p i sat in the back from sydney to adelaide not fun :p
