I'd offer 52K and they'll probably accept. If the carfax is clean, should be ok. Don't believe anything the salesman says however as you probably already know. That price is in line with the mileage but you may want to try a bit lower and leave them to think about it. Give them the buyers sob story about how far you are, how much it costs to ship, you can't see it in person...etc etc.
Remember these cars are moving like molasses up a hill in the middle of winter, you my friend, are in the drivers seat this time.
Good luck, nice ride!
