The 2021 Nissan Sentra looks seriously snazzy for a compact car that starts at just over $20,000. The second-smallest sedan in the Nissan lineup also matches its attractive outward appearance with a handsome interior. This makes it a more mature alternative to the youthful designs of the Honda Civic and Toyota Corolla. Unfortunately, the Sentra's superficial qualities don't translate into fun behind the wheel as well as, say, in the pretty and sporty Mazda 3. We're also not impressed with the Sentra's lethargic four-cylinder engine or the choppy ride rendered by the suspension in the sportiest SR model. Still, the 2021 Sentra will dutifully serve shoppers who prioritize interior comfort, safety features, and style.
