While I am not a fan of what you have done to the accord, keep it. What kind of Eclipse? RS? GS? GST? (doubtful) GSX? (even more doubtful)

Unless it is a GST or GSX you would essentially be trading for an equally as slow car with a weak transmission. If it is, then yeah go ahead and trade, but make sure to have enough money saved back for a 6 bolt motor when the engine decides to crankwalk on you.
