Mazda RX-7

From http://japanesenostalgiccar.com:

As you can see, this is no ordinary SA22C, but one flared-out in the Hot Wheels spirit of “speed, power and performance” with an aero kit inspired by the IMSA GTU RX-7 race cars. And of course, we are thrilled to see once again the JNC inkan on it, this time in gold on the B-pillar! To coincide with the release of this car a couple months from now, we will be releasing a limited edition gold version of our classic JNC inkan decal. Once again, we have to give a huge domo arigato to Hot Wheels designer Jun Imai for this incredible casting. He is really our advocate at Mattel, pushing for the inclusion of old school Japanese cars in the Hot Wheels lineup. The name on the car, B. Ozaki, belongs to Brandon Ozaki, who works in Mattel’s painting group and owns a widebody RX-7 himself. His son’s initials are also B. Ozaki and was born on the 20th, hence the #20 on the door.
