Rich You are going down the path that I have been mulling over (Cayman S to 997 turbo). I attended Reading OPC yesterday for an inspection/tour organised by R20. Talking to the mechanic when my car was in the air (nothing serious detected) we talked about my plans to make that same change. He said its (997T) a fantastic car, and one (a 911 turbo) that I have dreamed of owing for many many years, but very costly to maintain. Apparently a major service is £2k, owing to the fact that they have to take the engine apart to get at the spark pugs to replace them. We discussed alternatives and he considered the best value for money (I know running a 997 turbo was never going to be an exercise in prudent financial management!) is currently a 997 C2S PDK, servicing costs are modest, depreciation hits now being taken due to the 991 launch. All in all, I think I may change my Cayman S Tip for a PDK version of the same in a year or two. Enjoy your new toy when you get it, hope I've not put you off! David
