It's true; some enjoy the adventure of driving their own rides on road trips. If a Mercedes is being maintained well, it is most likely more reliable than other cars.

Only issue I can see is if you experience a MAJOR mechanical failure, i.e. transmission or engine takes a dump, you are pretty well stuck. If I knew there were reliable repair shops along my intended route of travel, I wouldn't have a problem traveling in an out-of-warranty mercedes benz.
