As I said in my 1st post, I rarely use the power, but it is nice to know it's there. I love the feel of the open air so the SRT6 would not be an option.
I know in my heart I would enjoy the XF, but it is just something about the prestige of the Vette family that I can't reject as quickly.

I have also owned a 350Z and RX8 so my other options in this category would be MB SLK, Honda 2000 and the Z4.

I am at that age where I want to drive a lot of different cars in a short period. Average ownership is roughly 1 1/2 years.
