Overall
Sentiment is highly fragmented and generation-dependent. For classic models (1967-1973), sentiment is overwhelmingly positive, with owners describing them as "sweet," "cool," and "completely reliable" vehicles with desirable V8 engines and strong collector appeal, particularly for special editions like the 1968 GT-E 427 and 1970 Eliminator. For the final "New Edge" generation (1999-2002), sentiment is sharply negative to dismissive.
Best version to buy
For classic models, the 1968 Mercury Cougar GT-E 427 and the 1970 Mercury Cougar Eliminator are highlighted as the most desirable, high-performance versions. For the final generation, no specific trim or version is recommended as "best." The V6 manual transmission is specifically criticized, with period reviews cited as recommending the automatic instead.

In stark contrast, the modern Eclipse Cross SUV (2018+) receives mixed to negative sentiment, widely criticized for the controversial reuse of the Eclipse name on a crossover, perceived sluggish performance, and underwhelming driving dynamics.
