Can I fly back to the U.S from a different city in Europe than Goteborg during Volvo Factory Delivery trip?

My grandfather and I were planning to drive across Sweden and Denmark in his new Volvo and then catch a plane to Paris. Volvo say that they pay for a round trip flight to Europe, but do we have to fly back to Goteborg and then fly back to the U.S? We just want to fly back to the U.S directly from Paris at the end of our vacation. I don't know how round trip flights work in that respect.|||You can fly back from wherever you want, but if you're driving the car you just picked up, you will have to get it back to Goteborg to be shipped. They are not going to come get it in Paris.
