Looking to buy 2004 Manual 6 spd as I posted on another question; the shifter boot is hard and turned yellow like;Gray interior, is this from the sun and normal; the salesman tried to tell me the leather is thicker on that side due to its use for reverse; sounds like BS to me; anyone with 6 speed seen this? They said they would dye it; I said REPLACE it....but they want to dye it
