Hey,
Glad to see another person is keeping their options open. I would be diehard american car... pre 1973.
Anyway, I think if you do a search on the threads I created, there is one about '02 --> 03 Vspec changes'.
From what I remember of the top of my head ( at work so no time to Cntrl N and mess around with cutting and pasting ) they sorta go like this:
* fixed some piston ring leaking there were with random oil consumption engines. I don't know if this has to do with improper break in, or just bad piston rings on Cylinder #1 in '02.
* Added a 6th gear to the V-spec and closer ratio gears. From all I heard, 6th is useless unless driving like a normal commuter/long trips.
* Gas milage is not as good as you think. You can probably get 25-30 depending on how/where you drive. It does have variable valve timing (as your prb know), so driving lower than the 4200... 4700 rmp valve change will prb net you better gas milage. It is a 2.4 L .. so it isnt a 1.6l gas sipper. Prb better than the Grand National

.
* No more lava interior. I don't know if that is good or bad for you, but I liked the lava.
* Torque steer: From everything I have asked, it is only when you get on it (free way ramps and light romps). You know where it comes from, so no explaination needed.
* Different packaging options. Now, sun roof is part of saftey package instead of audio package. More of the options are also standard equipment now leaving the option list relatively small for the V-spec... which is good. Price range is still nice.
* No aftermarket for the Q25 engine yet. The intake is new... springs from Ebach really arent on the right spring rates currently, ans Nismo is really vapor ware currently. You aren't really looking for aftermarket, alas, I digress...
* Arrest me yellow is now available for purchase!!
As for ride/power/anything else, I am not much help there. I am still in the 'I am ready, but I am flat broke' phase.
Good luck, and I hope whatever you get, you enjoy!!
