This is the third SUV, the idea also came from a pro LEGO&R builder- Ralph . His Yukon is the version in 2002, while mine one is in the year 2007.(latest one) It has a flipable rear seat, 5 openable door (include the rear door). The engine also the V8. And I also try to build a sun roof, but that is impossible!!(not just a spuare hole, must be openable)
