Mileage is the false metric on these cars. My 09 with 120K is in better shape (inside and out) that several 08/09 GTs ive thought about buying.
Maybe you could loosen up on the mileage req'mt the help your search efforts as well as the distance! At this point any factory warranty or even extended warranty is wearing thin so ensure maintenance is up to snuff. I saw a LGT with 109K on it for $12.5K maintenance records were solid!
There is a 2009 GRP Spec.B for sale locally that I drool over whenever I see it on AutoTrader mileage is in the 60K but its one owner and solid records. I love higher mileage car that are in great condition, just means they are built well for the test of time
