if you think the car is what you want go for it, it's a 2ss, that's a plus, I don't think mileage is as important as service history, if the car has a good record with 57,000 miles that's a good sign, people buy car all the time with low miles and find out they were traded in because they were lemons. the dealer probably can print the entire history of the car for you to check out.
