The accord is really nice, but:
Open differential (since the 3.2CL is gone how about honda puts the torque sensitive differential from TSX, TL in accord-for ~27 it should be there, the 2002+maxima 6manual has it)
215/50 17, good size for snow tires, 235swill fit the accord.
the brakes (pads) could be improved, the V6 manual has the biggest brakes of the current gen. accord, but the brakes are not a match for the newfound power.
The V6 manual takes premium, and the ignition timing is retarded when regular is used.
