Well if you're going to let your Insight rot away then for sure I'd recommend selling it.
A simple Google search has many - some of the highest being noise and vibration (buzzy engine + poor vehicle construction), poor build quality, and low safety ratings. There's a reason it has one of the poorest resale values of any car and why most people are eager to get rid of them before the 100K warrenty expires.
Vehicle History Reports rates the Mirage as a 4.2 out of 10--it's only saving grace is the 9/10 rating for fuel economy. Quality is a 4/10 and safety is a 3/10.
