Fed specs are faster due to less emision control I.E. only one CAT, better exhaust manifold ect ect... GTS are more on the power level of the fed spec GTs due to igher cmpression pistons now for the normal problems with the 3G eclipses
If you looked you would have found this answered by me in a thread like 2 days ago but ill copy and paiste it
If you plan to keep the car all stock it will be a great car for you. Common issues with these cars are only minor things. For example I got a list from the 2 I owned in the past.
Rotors will warp easily
Sunroof (if it has one) dont work all teh time the right way (they are fussy for some reason)
Power Door locks\alarm - will do what ever the hell it wants at times. It is supposes to beep and flash teh lights but from some reason it will work fine one day they next week it will only flash, then the week after that it will only beep (kinda weird but not a big deal)
the little red corner markers on the
rear bumper burn out often take a look at other 3G eclipses at night MOST of them only got one marker working lol)
factory are intake snorkel from some reason the plastic rivets holding it down inbetween the hood and
front bumper Break of or fall off (or someone doing a tune up removes them) and this causes the snokel to suction the hood on hard pulls and the car loses power (not to common but it happens, t happend to mine and a few other people I know)
The dash boards are weak up top near the windsheild they tend to crack easy (especially if you spin tires alot, most 3G eclipses have cracks or have been replaced, neither of mine cracked though)
The top center speaker for the stereo is junk it will blow out in a short time.
the In dash CD changer (if it got it) seems to skip alot even on brand new CDs (not sure if the 03-05s had that fixed or not though, and a GTS is an 03-05)
Headlights seem to peel no big deal just an eye sore to the anal people like myself.
I think that is about it... Ill add If I can think of anything else. but like I said nothing major just stupid little issues. They are great cars for daily driving.
