How frequently do we look at an automobile for sale and worry about whether it's been seriously damaged?

There are, however, skilled craftsmen, such as Arthur Tussik, a Russian guy who specializes in restoring, repainting, and fixing broken automobiles. He's now chosen to start a YouTube channel where he describes and displays how he works on the automobiles in his garage in great detail.
