21. Nissan Sentra SE-R
The early ’90s Sentra was notable for its bulletproof reliability and durability. But as the SE-R was released to the public, the car was a bit of a letdown. The SE-R lineup had previously been one of the most exciting parts of the Nissan line. The Sentra was lacking any real performance touches to make the car stand out from a run-of-the-mill Sentra. Sure, you had the bright red paint job and the DOHC engine, but aside from that, there was nothing unique.

There was so much hype surrounding the SE-R as the Nissan answer to the Civic Si. The car just needed a few more touches to take it over the edge. The performance wasn’t boring from the SE-R, but it also wasn’t exciting either, which left a bad impression on enthusiasts. To this day, the ’90s SE-R has a loyal following, but the car was a bit of a letdown in a multiple ways.
