I wouldn't do that test drive unless you're ready to buy, you may end up driving it home. Then the buyers remorse kicks in.There are some smoking hot deals on the TourX right now. I am just not ready and hope they makes some changes for 2020.
My 9-5 running well, rides like it is on rails and has all the room I need. A couple of cosmetic fixes and I am good to go for another couple of years.
Maybe I will at least drive the Buick...
For the cost of the license and a months payment, I bet you could get a lot of maintenance done on the 9-5.
