Fiesta III
This car has been in my family for 25 years. During this time, the number of breakdowns can be counted on one hand. It's a simple car, not overloaded with electronics. When newer cars failed, the Fiesta was always available. Nowadays, Fiesta Mk3s are rare, but they still look good (though clearly an old car). Few people would consider buying such a car these days, but I hope my opinion is still helpful to someone.
Pros:
Exceptional reliability, Simple, robust design, Timeless appearance
Cons:
Aging design, Limited availability today
