So several years we were wagon shopping and wondered if our two Great Pyrenees would fit in the back. We decided the only way to find out was to have them go with us to the dealership. We loaded them both up and drove to the dealer (we alerted our salesman we were coming). He gave us the keys and we tried it out. They fit fine and we bought the car. I'm sure they thought we were nuts but it answered the question.
"I was impressed by how well the cargo area fit one of my boxer dogs on a solo trip, and with one rear seat folded, both of my dogs enjoyed a short ride in the NX 200t. This isn't a full-size SUV, so large-dog lovers will likely be out of luck."
Hope you're golden retriever enjoys the ride when you get the nx200t
