Anyone that signs a legal document without reading it should be removed from the gene pool.

As for shonky dealers etc, anyone that has worked in the panel and paint industry can tell you about new cars that are repaired and put back on the lot like nothing ever happened.
When I was an apprentice still, we had a EL XR8 come in minus a front bumper and lower rad support damage. Apparently the car carrier had turned too soon and dropped off the ramps on his truck. We fixed the damage, put on a new bumper and when it was done I was given the dealer plates and told to drive it back to centre ford. I had only had my license a few weeks at that point and it was wet. I was shitting myself every corner!!!
