20: Ford Probe
Just the nameplate alone was enough to scare potential buyers away, but that wasn’t the only thing that was wrong with the Probe. The car had a design that was cheap and didn’t add up to what the company was portraying. There were some in Ford who was positioning the Probe as the modern Mustang replacement. That never happened and Ford ended up having two similar sports cars in the lineup. Although the Mustang always had a V8 powerplant, the Probe received a turbocharged V6.
There is no denying that the Probe had some serious potential, but it wasn’t enough to warrant phasing out the Mustang. Had the Probe have had a better design and reception the car would have probably sold a lot better. Nevertheless, the Probe is a failed experiment in creating an appealing sports car.
