CJ, here's a thought.
As a baseline, try out the CTS 3.6DI RWD. I took delivery of one 10 days ago (the AWD model) and so far I'm very impressed! GM really did build a world class car! You can get an idea of how the "lesser" model drives and handles and then calibrate up one or two logarithmic scales for the V version.

I REALLY wanted a V, but it's not in the equation right now as I need an AWD vehicle.

I'm watching the V forum with great envy as I see the cars ready for delivery, and imagine the lucky folks driving them shortly. If ever GM ever decides to make an AWD version of the V, the day I find out, I'll be at the dealer putting down my deposit and trading in the CTS, no question--no hesitation--test drive or not!!
