Hi, I wanted to post part of an email that I received from the person who created this model. I had just gotten it back together after re-wiring it so I took some pics with the lights on. The doors and hood are all counter-balanced with stainless steel brush wire so they actually stay up by themselves. They also have latches so they stay closed. The seats slide back and forth. The suspension actually works. If I recall, each of the gas struts is actually 5 pieces, and they actually slide in and out with a little resistance. The pullstraps on the doors are actually through the door handle. 19 working light bulbs, and 4 working earbud speakers are inside. Erik
