Great power, Poor ergonomics
 Have had this car for 2+ years and my lease is up in May, 2010.  I was thinking about doing a buy-out but I just can't get past the interior ergonomics.  There is zero storage space to put anything.  The cup holders are cheap and pop out from the dash.  There is nowhere to put sunglasses, maps, coins, receipts, over-sized bottles, etc.  There is also no rear seat leg room.  The car itself is undeniably the best performance vehicle in its class. The twin turbo is an absolute joy to drive with unmatched power.  I will miss it but, again, I can't deal with the interior anymore.  BTW, the I-Drive system is easy to figure out but it's slow as molasses.
