I have have never had a Honda.
You are scaring me talking about rattles.
They are very annoying.
Here are my experiences with rattles . . .
I had a Honda 2000 CR-V that I pulled behind a motorhome. On top of its use as a toad, I drove it another 125,000 miles without any rattles. Although certainly underpowered, it was a solid little car.
I also had a 1996 Honda Accord for 4 years before the CR-V. It had ample power and for those 4 years, I didn't have a single rattle. Again, it was a solid little car.
Now, I have a 2010 RL RTL. Although it's still brand new with only 1000 miles on it over the past couple weeks, it has yet to show any rattles. The build quality feels and looks very similar to my previous Hondas - perhaps even more solid in some ways. The dash feels firm, the doors shut tight and everything is working, closing, opening, turning and performing as it should. It feels just as solid as my previous Hondas, perhaps even more so in many ways, so I don't expect it to become a rattle-trap.
I hope my expereinces have calmed your fears somewhat.
