From an article from YourMechanic:
Luxury imports from Germany, such as BMW and Mercedes-Benz, along with domestic luxury brand Cadillac, are the most expensive. A Toyota is about $10,000 less expensive over 10 years, just in terms of maintenance.
Toyota is by far the most economical manufacturer. Scion and Lexus, the second and third most inexpensive brands, are both made by Toyota. Together, all three are 10% below the average cost.
