Rear Ended 2 weeks ago when stop at a right turn lane waiting for traffic to emerge and 2 seconds later BOOM! rear ended ...

Car was push about 10 feets forward and the car that hit me was Dodge truck (no dent to his truck of course) he's going about 20mph.

His insurance USAA called me and claim full liability and got me a rental car. The car is currently in the infiniti approved shop since last monday and total cost of repair is about $6500 worth of damage.

USAA is sending me a Inherent Diminished Value forms and will do their own investigation to see how much the car depreciated.

Only owned the car for about 6 month and bought it at 6k miles...

Anyone know an estimated I'd get for the diminished value?
My G is fully loaded with Navi, premium, illu kickplates, and sports package.
I'm also looking at just trading in or selling the car right after repair because it just feel different after the car has been hit and there are uni-body damages done according to the shop.
