I'll be harsh but honest - you did say "go ahead, tear it apart"
And I'll try to be helpful too...
The colour scheme is not attractive at all. Try Adobe Color for some inspiration, or use the Color Guide panel in Illustrator to find complementing colours.
Too many textures and effects. Outlined text, blue pattern background, grey/white gradient background, brushed metal background. Simplify it, and if you want to show off something like metallic vinyl, put it on one element so it stands out, instead of the top 1/3 of the whole vehicle.
Also, the font in your logo is about as generic as you can get for a sign shop. That style is way too overdone (the square-ish letters like Eurostile/Microgramma etc.) and looks quite dated.
