Here's the solution:

Get an Accord EX V6 6 speed with the HFP (Honda Factory Performance) suspension kit (lowered springs, better struts).

The HFP kit is about $1700.00 installed. You'd then have a car with power and handling that would blow away the TSX.

Not to mention, when you get to the EX level Accords, you really are at entry level luxury. Features wise, the Accord is missing the 3 position drivers memory, power passenger seat (on coupe - sedans do have a power passenger seat), auto dimming rear view mirror (available as an accessory, though), and Xenon gas HID head lamps. If those aren't that important features to you, the Accord V6 and TSX may be a wash.
