For MO, you send the title in and they send it back with your new plates. These cost something like $25, do not expire and no inspection is needed then or ever again.

They also come with a log book. You are allowed a number of miles for unlimited use. I think it is 2K miles. Might be 1K. Driving to and from and in car shows or races does not come off of your allotment, but driving to work would.
