16. Saturn S-Series
The Saturn S-Series broke new ground in the 1990s with its innovative use of polymer body panels mounted on a steel spaceframe. These panels made the cars highly resistant to rust and minor dents, drastically reducing long-term maintenance costs.
This clever engineering allowed Saturn owners to enjoy both durability and affordability, while the simple construction made repairs straightforward and inexpensive.
