Is the 2013 Honda fit with over 50k miles on its clock reliable enough to make a 1000-km road trip?

If it has been maintained properly (no maintenance records, assume no maintenance) - I do my own maintenance and have everything logged by date, odo reading, service performed, brands and other pertinent data of products used. So there should be some kind of records or service invoices etc.
If well maintained - I wouldn't hesitate to take that vehicle for a 10,000 mile trip.

I don't know why it wouldnt be ok, Hondas are barely broke in at 50k miles.

Certainly should be, if it has been properly and fully serviced and maintained throughout those 50k miles.
