5: Maserati Bi-Turbo
The Maserati Bi-Turbo was another failed attempt at a luxury car brand to create an affordable offering. The first thing you notice about the Bi-Turbo is that it was short and stubby. The car didn’t do much in terms of performance, and buyers couldn’t get over the sights. Another thing that the Bi-Turbo did wrong was the interior volume (via Car Gurus).

For a car in this price range, interior space was at a minimum, and that’s never a good thing. The Bi-Turbo could have been a winner for Maserati, but instead, it was a dud. The maintenance issues and lack of refinement caused the car to fail. These days, the Bi-Turbo has become a collector’s item due to its novelty appeal.
