What is the name of this font? Please

Cabriolet  Sugerido por donshottype 

These car logos were not fonts. Font Diner has a few fonts in that style: Rocket Script on dafont and some commercial ones on myfonts.com: Emblem Chief, Permanent Waves.

The chrome emblems of 1950s vintage cars have inspired several connected geometric scripts, including the ones mentioned by elzada.
The closest to Customline could perhaps be Cabriolet and Hooptie Script Italic http://myfonts.us/td-jkuh6m
