I was also looking at the Mazda 6. I must say it is a one sexy car, just don't get the first year it came out. Have to work out all the bugs. Make sure you get it in a manual so you can actually feel the gain. Those duratec motors from what i here are pretty damn strong. Check this link out for some mods out and listen to how this car sound with I/H/E. That alone makes me want it even more.
