Wow not bad. I bought my 2001 GSR coupe this past january and it had 2800 miles and it came with eibach lowering springs, tokiko struts, AEM CAI, 17" rims. I got it for $20,000, so that is a pretty good deal I think. Good luck if you get it. Have fun with it.
I have a 2000gsr and the only way i'll sell it is for $20,000 w/ mods of course. I think 18500 is a pretty good deal since our Honda engines are pretty reliable and our tegs are pretty hard to find. I'd say go for it.
