I just looked up the resale value of the GSR you are looking at and it said $9,400. You should be able to talk the seller down on that car...I would think a grand or two. However...even if you were to buy the car as is the difference in price b/w the two is only $440, and there is no performance mod that I know of for that much money that would give an LS the performance of a GSR.
