If you have a sense of adventure and time to explore, historic highway 50 out of the Bay area. Been a few years since I took that route, prior to Covid, so not sure what to expect today. There are some historic spots, especially once in Nevada. In Utah, you will take 15 for a short period to 70. Then on to 191, takes you through Moab- stunning vistas, 46/90 then 145 into Telluride. There are adequate fueling stations, lodging and food. Sublime trip in a M5. I might add, a M5 that is well sorted prior to taking this route. It gets hot through Nevada/Utah, early morning starts can make a difference, mechanical and personal.
I’m stopping in Fallon, or Ely NV on this route. There is a Holiday Inn Express. Book as soon as you can, for they book up.
Scipio Utah would be a good place for spending the night. Scipio hotel is good.
If comfort and services are your priority, 80 to Salt Lake, 15 to 70 to 19. You will go through Moab on this route too.
There are Holiday Inn Express-Hampton Inn and Best Western along this route, judge your driving distances for the day, and book early. They book up in these parts.
Have fun!
