I was thinking you are having a buyer's remorse as well. But I am trying to look at your perspective as well. Perhaps, you were expecting too much from what you have purchased.
I have an 18 MDX Tech Hybrid, and the initial impression was the most cushy ride I have ever experienced from a Honda car. It was, until my nth time passing by NYC. Made me realized how ugly the roads are in that city. I remember driving a Lincoln Navigator once several years back. The ride was so comfy until I drove around Manhattan. The bumps were bone jarring experience, most especially when you hit a path hole that is wide. Until now, I can still feel how the steering wheel felt. But that was some years ago. Nothing will escape the NYC path holes. I don't like driving in that crater-filled city.
Coming from a CRV, Civic, Odyssey, Civic Si and 07 RDX, my MDX feels so comfortable by many miles. Perhaps, I have never put any expectations on my MDX. But perhaps, the suspension was way different from my other and previous vehicles.
not everyone enjoys a rough ride. An access cover sticking 1'" above grade will toss me from side to side when I hit it at 35 mph. After a series of bumps like that I am ready to toss the MDX but it is owned and the financial loss would be significant. Shame on me for not catching that before buying it.
