The industry standard is between 30-35 miles per hour. Thus, your engine theoretically has 120,000-140,000 miles on it. Thats a ton of idling time, thats for damn sure.
I work as a govt fleet mechanic and we use the 35 mph standard as we have a ton of cop cars that sit idling at intersections 24 hours a day thus, the mileage is useless to us when determining when a vehicle needs maintenance.
I wont say you got a lemon but, you definitely dont have a 55K mileage vehicle in your possession.
As for rust underneath, Im calling bullshit on that being normal. I live in the North East where you drive on layers of salt all winter long, and there isnt a spot of rust on my 2016.
Any chance you can refuse the sale and send it back? Unless you got it for a steal of a price, Id be very worried if I were you.
