The Aviator was another well-known Lincoln model in the early 2000s. The company hoped to build on the success of Navigator with a midsize offering. The Aviator was not popular due to the high price tag and lack of features. The Aviator also lacked the reliability of other well-known offerings in the segment (via Readers Digest).
For the price of an Aviator, consumers could just opt for the full-sized Navigator. There were other offerings in the segment that was more reliable and offered more features. The final blow for the Aviator came when it was discontinued a few years later.
