willieace, the yellow #66 Mazda RX 500 all the way at the right is the only non-streaker.
Streakers were the cars Hotwheelergeo listed and had the tampos (graffix) as shown in the picture.
The remainder of Lesney's 1-75 line-up did not have these tampoes...thankfully.

And you could find most if not all of these models pre-'75 without the tampos.
