I say dress nice and show up, you may still not know what to expect after a bunch of internet advice.
I fought a ticked (expired inspection) and won, it helped that I got inspected a couple days later. Another officer represented the entire town department and there was opportunity to discuss the case before going into court. I was better dressed, respectful, and prepared than 95% of the other bozos waiting there and got off.
Incidentally, the judge did dismiss cases from towns without police representatives... no continuances... the day's slate was wiped clean. YMMV.
