honestly if i was in the market for an GSR with those miles, i wouldn't mind paying up to 6K, i say go for it. do you have any info about the motor? if everything is fine buy it man, the other day i saw an 1999 White GSR with 97,000 exact miles for $7,200 at an local dealer. so that price isnt bad at all, just my $0.02, good luck with the buy man.
