A suspended registration can turn a normal day into a mess. You get pulled over for a broken taillight, then the officer sees the registration status and the stop gets bigger,

Clear coat peeling means the paint’s UV shield has failed; repair small spots early with sanding and recoat, or repaint the panel if peeling is wide.
