2020 BMW 3 Series Reviews SummaryDoes BMW still use “The Ultimate Driving Machine” as its advertising tagline? Yes, it does. And with the arrival of the 2020 BMW M340i, which slots between the existing 330i and the forthcoming BMW M3, the company proves there is substance behind the slogan. | |
2021 Nissan Sentra Reviews SummaryFollowing a makeover for the 2020 model year, the Nissan Sentra has ripened into a prime specimen of the compact sedan genre. With competitive safety, technology, and fuel efficiency now supplemented by an attractive exterior and interior design, the Sentra no longer feels like a compromise—it feels like a smart choice. | |
