I've kinda come down to this then...and I do agree it is harder to compare the new 2003 accord to the "old" TL. It will be much easier to figure out when "new" TL comes out.

I was using Edmunds TMV price & then added tax for both 2003 Accord EX V6 Sedan and for 2003 Acura TL Sedan. and I came up with $3356 difference. Below is what I've justified as the prices for the "upgrades" so far. Still 2000$ difference that I haven't placed yet... Honda helped themselves a lot by making heated seats =) as that was another 500$ in my mind. I've left out subjective matters and was just going by materials and features.

HID lights (500$)
Fog lights (250$)
Bose Sound (250$)
14000 miles longer warranty (218$)
Driver Seat Memory (100$)

2038$ still left to figure out premium... like i said, this will be much easier to figure out come Fall/Winter. I think that I'll be able to name a lot more with a price come that time and it may only be a 500-1000$ premium.

Hope my jibberish isn't too confusing.
