6: Ford Taurus SHO (Third Generation)
To boost the likeability of the Taurus brand in the 1990s, Ford attempted a performance model of the oval Taurus. This variation of the SHO had a V8 engine sourced from Yamaha. The performance was more than adequate but it wasn’t enough to bolster the brand during this period.

The Yamaha V8 had a lot of reliability issues and the car became more of a lemon than a collector’s item. The SHO was generally a well-liked brand but what happened with this generation tarnished it forever. You’d think that putting a V8 powerplant in a Taurus would be a fun thing to do, but the reality is it wasn’t.
