so my buddy has an 03 cbr that has been laid down b4 with 11,000 and he really didn't care much about it as in he would leave it out in the rain and snow. The bike appears to run fine since I go riding with him occasionally and i've ridden it b4. So my question is... He said he want to sell it and he said he would give it to me for 2500. Should I buy it or what?
