I think I'll have to order a few hammock style covers and see how they do. Just have to make sure I have full seat belt access so I can buckle him in. Nothing better than taking your best friend out with you in a nice drive, IMO. When we go out to hike in the mountains I want to take the M3 on those roads, not my Volvo!
He does really well in the car, even on semi-spirited drives. Used to take him out in my Shelby all the time, buckled in the front seat with a cover. Nice thing with the M3 is now I can bring my wife along comfortably as well… maybe I'll just make her sit in the back and let him sit up front.
