Entry#4: Great start. We like the look so far - we would like to spruce up the Tag Line a bit more on all designs. also possibly some different variations of the grey box background behind the logos.. maybe not so simple but not necessarily the diamond look either - more options with similar feel would be nice to see. like the direction here.
Doncorvair's - we mentioned an idea in the description about incorporating a part into our logo similar to how you've done with UC Irvine Cleantech and Energy - we can send images of Commercial Vehicle Parts if needed - otherwise a Cargo Van Part of some sort could be used for examples...
Entry #10: This logo thus far has touched on many areas we feel are important to our goal. The Parts logo font is good, it stands out from the rest of the logo design but does not over power the rest - try to enhance the "parts" portion with more borders or a more glossy look - almost reflective? The tagline is placed nicely and stands out on the tire - the background resembles a part from a van / truck and looks like an actual tire. Maybe more enhancements throughout - basically touching up with better details throughout entire logo.
Entry#11: We do like the diamond plate look - definitely matches our industry. We would like the tag line to stand out a bit more on this design. Also - maybe the parts portion on this logo is too big and overpowers the rest of the logo..also would like a better looking "parts" logo - font is nice - but more enhancements to it maybe.
