Danger Will Robinson!!! Considering what pieces of crap I’ve seen sold on bring a trailer, mid $50s is way underpriced, for the supposed condition it is.
For that price, and 1.5 hours away, I’d make a beeline to look at it with cash in hand.
Googling the VIN, it comes up with one place in Texas selling it. No other links.
