Interesting to hear a blanket condemnation of Bayliners in 2018. I started listening to criticisms of various manufacturers before having a boat built for myself and my wife, in 1977. The Bayliner rant was around then, accompanied by examples to justify the rant itself. Eventually, Bayliner got the message and cleaned up questionable cost saving methods, if they ever were the problem, but the rants continued.
After so many years of pushing back against that rant, Meridian was formed. That change was needed, and the "new" company survived well for a few years, with only a few rants of "it is really just a Bayliner" following.
Now you can't get a new Meridian either, so anyone with a rant against Bayliner is talking only about fairly old boats. Those old boats have now been tested for long enough that any real problems that could be attributed to the manufacturer have been taken care of. Any existing problems can be attributed to maintenance, or lack thereof more than to the generic brand name.
Gross generalization, I know.
