5: Citroën SM
This car has recently come into the limelight because Jay Leno is the proud owner of one. This was one of the first mainstream French sports cars to hit the market, but that is about all that was good about it. The design of the Citroën SM was questionable at best and it didn’t catch on with many consumers (via Hagerty).

There were some interesting features of this car, but nothing worth the high price tag it commands today. The Citroën SM is one of the most overrated sports cars from this era. This is also one of the least common sports cars from this period, and if you see one on the road, it stands out.
