Welcome Rich, like you I came from an 04 TL and live in the No. VA area, I definitely can relate to how you feel about the new G35. I'm still smiling everyday even after 9 months.

I commute to DC on mornings using the GW Parkway, I agree it is a breathtaking view of the Potomac and Washington especially before the 395 bridge. Congrats and enjoy the ride.
