Before long we'll all have you scrapping the whole thing and starting over. It looks really good and just needs a few minor tweaks to maximize effectiveness and reduce some competition among messages you've created.
Dump the "Call" "Call today", etc... it just muddies the message. The great Ken Millar once did an awesome article in Signcraft about legibility. He actually broke it down into seconds on how the human eye can perceive and absorb things and at what sizes text can be read at. There are "eye candy" elements we ALL put in signs to make them look better, and there are fundamental elements that should be in every sign.
I know you're going for a retro, classic look, but humans just don't think like that at 65 MPH anymore. Back when work trucks tooled around city streets at 25-30, streets were narrower and phones were in houses not people's pockets, folks needed a little prod to call.
I agree with the comment about your white services text competing with your main icon.
