there is no GSR special edition.

throughout the whole integra lineup, there is the RS, LS, GS, Special Edition, GS-R, Type R.

the GS-R and Type R are the only two integra that come with the DOHC VTEC engine. the others are DOHC, non-VTEC.

the RS - GS (Special Ed.) you have the basically the same car, but with different options such as leather, sunroof...blah blah. and the RS doesnt have ABS. thats as much as i can remember.

and yes, i would say that is overpriced for a 3 year old integra.
