Assuming it doesn't have any scary accidents in it's history, up here that car would be worth $2200-$2700. That exact car except with 108k miles was just listed for $3500 and sold here for close to it a few weeks ago. So if you double the mileage, I would think the pricing correction would be $500-$1000 depending on just how nice the rest of the car was, any available service history, and just how uncommon they are in your neck of the woods. Just my 2 cents but I hope that helps
