I went to the CSX Launch Party back in Nov and got to test drive it. I don't know but the extra hp is negated by the extra weight. I tested the new Civic EX already in October so I knew what to expect when entering the CSX. It doesn't feel any more powerful than the Civic. Also, torque is a bit weak under 4000 rpm (I think VTEC kicks in around 3,800rpm). The paddle shifters shift quite quickly, better than the IS250/350 (sadly) I tested also back in October. I think the prices between the trim levels are reasonable but the base price of $25k is a bit steep. I mean, I remember when a 1.6EL started at $18k! haha.
The Civic EX manual at $22,180 ($23,380 for auto) works just fine. All I get for the extar $3k ($4k if you subtract the moonroof from the EX), is an Acura badge, a bigger engine (no difference as I tested it), automatic climate control and integrated turn signals on the mirrors.
The old EL, has much as it was a Civic, still had a low price that made it attractive. Don't tell me Acura jacks the price up just because it wants to become more of a premium brand (RSX price jumped from $25k to $27,200 for the 05 model.)
