At this point in the game, you don't want to bite off more than you can chew. Concentrate on just your lettering, and get a better handle on that. I'll give you a hint. Look at most major brands out there, Do you see them using crazy gothic style or stenciled looking fonts? No. Why do you think that is?
You don't need the strangest looking fonts to get peoples attention. It doesn't really work that way. You want clean, you want easy to read, you want a font style that matches the overall style for your business. Perhaps that is where you should start.
You are working on cars right? For the most part cars are sleek sexy and stylized. They have a flowing design where everything fits together right? If I were you, I would try to capture that in you logo. Perhaps looking through car emblems might help get your juices flowing.
95% of the fonts that are out there are worthless for most designs, unless a specific style calls for that unusual font. So make sure the font style makes sense with the other elements in your design but most importantly makes sense with your business.
Next you are going to want to focus on contrast. That is something that even some long time sign folk struggle with. White on light blue does not have enough contrast. My tip for this is to first do a search on this site for "squint test". Get in a habit of designing and thinking in black and white. Most of the time a logo that reads well in black and white, well also read well in color, and that is because of contrast. Once you have a solid design that works well in black and white, come back in and start adding color, Make your blacks dark colors and your whites light colors. There is a bit more to it then that, but at least that will get you started.
