Should You Use Unique Title Tags For A Crowded Industry Or Not?

In the 273rd episode of Semantic Mastery’s weekly Hump Day Hangouts, one participant asked if one should use unique title tags for a crowded industry or not.

The exact question was:

Hey guys, when it comes to Title Tags for a crowded industry, do I have to have a unique one? My car dealer client is in a big city, and all the page 1 companies seem to have some variation of New Cars in City, or New, Used Cars in City. Usually I try to make my title tags stand out, but in this case should I just copy what the competition is doing? Is my focus on uniqueness even justified? I don’t remember learning it.
