The interior has held up fine. Some of the black surface on the dashboard chipped off. It was about the size of a nickel. But that was my fault for allowing a GPS unit to be too close to the dashboard. I got the car December 6, 2013, so I am in the last year of my 2-year lease extension. If they offer me additional time, I will most probably take it. If I don't take it, it will only be because I switch to the Clarity BEV. The only mechanical problem was a yellow light bulb burned out in the right front turn signal socket a couple of years ago, which Honda replaced at its cost (probably 15 cents for the bulb).
I am amazed at how well Honda built this car, especially given that it was a "conversion" from an ICE car. I have nothing but the highest praise for Honda.
