I keep 4 vehicles that I paid cash for:
1. 2000 Honda Odyssey (165k, 18.5 mpg) used for helping kids and friends move, Home Depot runs, etc;
2. 2002 Toyota Camry (120 k, 27 mpg) younger son uses when home from college, I use when he is in college;
3. 2003 Toyota Corolla (60k, 30 mpg); older son uses as needed [no parking or need of car in town where he lives], I use this when son is not using. Also loan out to friends whose own car is in shop; and
4. 2012 Toyota Prius (25k, 52 mpg) wife uses exclusively as a commuting vehicle.
If one of the cars breaks down or requires maintenance, it is put aside until the necessary work on it can be done, and another is used. As I do most of the repair/maintenance work, this strategy has saved thousands through the years with little stress. Also, insurance premiums on cars 1,2, and 3 are at a minimum.
