Currently in the process of accepting a new job and I’ve come to the realization that I will be putting near DOUBLE the miles on my precious Bimmerrrrrr...... So I have a question for my fellow opponauts. What would be a reasonably priced (new or used) highway cruiser that I can load the miles on and still get reasonable gas mileage? Not really looking for another luxury car, but I would want a car that can handle 80ish without screaming at 4k rpm. (preferably option for manual)

Thank you!!
