Which car is faster between the two?

I want a car that is reliable, comfortable, good looking, and have powerful performance.

Anyways my question is which car is better AND faster between the two?

The 2013 g37 sedan or 2015 Honda accord ex-l v6

My moon roof won't open at all, 2007 honda accord EX?

Ok, so I recently had a new ECU placed in my car, reprogrammed and what not, because some idiots blew it out, jump-starting my car, so anyways, I took it to a honda dealer to get it fixed. Well it runs now, problem is, my moon roof won't open. It doesn't even make a sound like maybe it's stuck. Could they have blown out the morter on it? Or do I need to reprogram my moonroof, as I've read online? How would I know either way if it's one or the other?

Should I get a mazda or a honda?

I've found a 2006 honda accord ex coupe and a 2008 mazda 6 i sport value edition. They are both about the same price with about the same miles and they are both in really good condition so I can't decide which one to get. What would you choose and why?
