I like alisonj's advice. Take him in the car when it's not running and give him a treat. Then let him out. Do it again and again. Make going to the car fun.

I don't have any experience with dogs that get carsick. I like your idea of getting a carseat that he can see out of.

If carsickness is a problem, I'd try taking some short trips to get him used to driving.

Good luck, and let us know how it goes.
