how man were sold in 1978 in the u.s.

Hi silverado, This information is not readily available on the internet. I would recommend that you contact Mazda corporate to have your question answered. Good luck!

I think you could refer 2 wikipedia for that. They have a list of the sales figures for the RX7 and alot of other cars.

actually none, the rx7 began in 1979.

The 1979 model year would make it available in '78 dude.
