To @anulfo de l.a. 's point, I started noticing in the 1980s, in Hemmings ads, that people (who apparently could not work on their cars OR if they might know how) would start to use the term "Professionally rebuilt" as to carb work and anything mechanical. In reality, that meant they paid somebody money to do something for which they got a receipt. No more, no less. Allegedly supposed to mean it was "done right by somebody that knew how to do it", BUT we all know how variable that cian be. OR they'd mention the name of the entity that did the work, as if that might mean something to somebody, as in added credibility it was done well. Still variable as to whom in the shop did it, unfortunately.
Just some observations,
