I wonder how old these cars will need to be before people stop thinking of anything over 50k miles as "high mileage"? that car is over 7 years old so i think the mileage is fine, they're a GT built for doing mileage, they're not a delicate sports car. Mine is an 06 and has now done 63k miles, i suspect by the time i'm done with it it'll have over 100k an be worth about 50p whilst the few that are left with under 50k will be worth £20k+ i guess only the buyer can decide on if the price premium is worth it
personally i bought the car to drive, that obviously means putting miles on it and lowering it's value, but that's fine as when i paid for the car i wrote off that money in the same way you do when buying a TV, it's resale value is of little concern to me, i'm not wealthy but i also don't want the worry of future values impacting on my enjoyment of the car
If that car is straight i think it's a bargain, i can't see a GS of any mileage being worth less than 10k, surely one must break for over £5k?
