its a pain in the ass to keep going back and forth from the computer to get new parts. maybe they should have a faster way of ordering parts from the computer. like a automatic replace all parts or have a system where I can ether right click and it will give me the opition to gain a indivial part that is need right then in there with out having to go back to the computer. not saying the should get rid of the computer section but to make it faster and maybe it can eve make for more complex building of cars like more detailed interior wiring and actusal test builds and more in depth details of the cars and their parts like puting on the lights through the head lamp retainters and actusually bolting of the engines. to make this more complex mechanic builds. so quicker parts purchase and more complex simulations.
