Again, it's a bad idea your cars objects will have very poor positioning because editing objects in this way has absolutely no precision so if you have say two of the same objects offset on the x-axis they will never align correctly. I really don't see doing this offering much reward for the effort involved. The fact that no one has really done it yet should be a sign enough given the multiple unsuccessful attempts that it is a bad idea just use commands.
