To answer your question...
We didn't make the rule that people have to have "nice cars" in order to enter. Instead, it was one of the most common critiques we heard of the ROTM contests we were running. "This is pointless. There's only one nice car here and it's going to win." I personally don't care who enters, as long as someone enters.. and that is the problem. Very few people enter.
A lot of you support doing it quarterly, but we tried that too, and it STILL didn't get a sufficient turnout. That is why we're re-introducing featured ride. It happens whenever there are worthy cars, and it's more in depth, with better rewards.
