TIME IS MONEY. Every minute you spend dicking around with a car that is down 1000 miles from the house is a minute you could be doing something productive. You just became a slave to the car.

I've lived this situation; after I received sticker shock from the out-of-state stealership for mercedes benz repairs, I limped home. Fortunately, the car made it but the return trip was touch and go. Now, if your benz is under warranty that is a different scenario. Even then, it could take a week if they have to order parts from Germany

Instead, rent a car from a car rental company and enjoy the trip instead of dealing with mechanical issues. Nowadays, you get your choice of rides, some of which are really really nice. Next trip, I'm thinking of renting a motor home and dragging half the neighborhood along with me! ROAD PARTY!!!!
