Nice work on this, love the rain on the windscreen. Did you use the Ford Explorers and fences from here? https://3dwarehouse.sketchup.com/model/e04148eb-77da-4b9f-8e71-881fbc72e2c8/Jura... ?
Thank you.. Yup, I did use only car models and I modified them so that you can open and close the door.
Thanks for getting back to me. I have 100% accurate Ford Explorers with full interiors, if you'd
like to use them I'd be happy to help. I've also built several scenes from JP here http://www.sketchfab.com/paulelderdesign
