From one newbie to another, welcome.
I have always liked the Accord but when the new 7th gen came around, that was just a pure gimme. And lo and behold, I think we got the exact same car

Me personally, I would stick to 17s and really good tires, and then lower it just a tad. My own reason is because I use it for commuting purposes. In fact, I don't even know if I'm going to go with 17s because you lose a lot of the tire "shock absorbing" factor since there is less wheel wall. So maybe I'll stick to 16s.
So far, I have had the car for about two weeks and it has 1200 miles!!!

See what I mean about it being a commuter?? hehehe...
