The Logo with the chrome and the car looks more like an automotive logo, the first logo reminds me of Adidas or a delivery service or flying if it didn't say automotive i would walk past it at a distance.
I think you should be looking at which logo is best for your target market, the first would be perfect for old fashion car restoration however the 2nd may appeal to younger market.
The first one will be much harder to work with for branding. Square logos that contain the text within the design are really hard to fit into a wide range of places. You'll be stuck making the logo small for any rectangular spots. I think you're close, but keep at it.
Both look good, but the second one looks professional. first one is good for design, but not for logo.
