This is another series that could use Diorama's. Like a station wagon with a family(little plastic fig's). Standing by a guard rail(also plastic). Looking at the grand canyon(Which would be a real pic). Also include luggage rack, bike rack, U-Haul trailers, etc. Other land marks could include baseball, football statiums etc. Landmarks in other countries and use the VW's or the Citroen. All it takes is a little imagination.
The Autobaun would be cool. Little plastic AB signs. Use the GT casting. Thats a cool "road trip".
OK OK OK Here it is. The mother of all dio's. A "Road Trip" LIGHTNING FEST thank you DIO set. Cars included would be "YCITS" of coarse. Fig's would include Mark and other LF heavy hitters. Hopfully inclucing the american beauties.
