4: 2007 Nissan Sentra SE-R
In the mid-2000s, there were all-kind compact cars catering to the tuning market. Whether it was the Dodge Neon SRT or the Mitsubishi Lancer Ralliart. Nissan figured they’d throw their hat into the race. The Sentra SE-R had a good concept, but the end result was lacking in several areas (via Car and Driver).
For starters, the SE-R was more of an appearance package than anything. Nissan didn’t up the ante with any sort of performance enhancement. This meant that while the badge on the car read “SE-R”, there was no performance enhancement to speak of. The Sentra has never been considered a sports car, but Nissan missed the mark with this one.
