2015 TDI Passat manual transmission

Hi,
Looking for some advice. Almost 2 years ago I traded in my 2011 diesel Jetta in the buy back from VW. Took the generous buy back cash.
The 2015 TDI's just came into thier stock at the dealer. Bought a 2015 TDI Passat. 6 speed manual transmission. It was a great deal, 5k off sticker and 0 financing. Love the car.

However, I need to give it up, as I tore a ligament in my left knee, and shifting is out of the question now and for the future. Luckily I have another vehicle to drive. (Truck)

I am not sure what I should do to sell it. Trade it in, or sell outright. Need to check the milage, but it is under 20k. Not sure if I will buy another vw, I really love the tdi, but need to check inventory around here. (NY) I definitely want to get in a car again.

Thanks for any advice or thoughts you might have.
