The car I believe to be the most overrated is the Delorean. That car was poorly built, overpriced, and underpowered. Yet so many people were very excited about getting the car, thanks to the Back to the Future movie series, which featured a Delorean modified into a time machine. However, it was styled by well known Italian styling studio Giugiaro, making it cool looking.
The C4 Corvette (excluding the ZR1), was a close contender. Remember this was an era when they came with 250 hp V8s.
