I cross shopped the R8, F430, and the Gallardo before deciding on the 997 911 Turbo. If you can, I would highly recommend the Turbo. Best car I have ever owned, hands down. Unfortunately with 3 small kids and the role as family man, it was time to move to a more family friendly ride, but I miss my 911 every day. I told my wife that I am buying a 997.2 Turbo S on my fortieth birthday. She agreed, but it's going to be a long four year wait.
