3. Dome Zero
You may remember this car if you grew up in the late ‘70s or early ‘80s. It was one of the first Japanese supercars with a memorable design. The Dome Zero was a small Japanese car company dedicated to producing expensive road-going and race models. Production started in 1976 and continued until 1986, but it is unclear how many cars they built.

The Dome Zero came with a 2.8-liter SOHC six-cylinder engine with 147 HP. Although that doesn’t sound like much, the car was extremely light, so the performance was respectable. Unfortunately, Zero never completed the homologation process, so their racing career was short and unsuccessful.
