I don't personally dislike the background. It's not my style, but it's contemporary and trendy right now so it's not bad. Very busy but for that grunge style it works.
I agree with everybody else that the typography on "Premier" needs help. The actual logo. I see what you're going for with it but if typography isn't your thing, you might want to enlist the help of someone who can take your initial concept and redo the logo so it's a bit cleaner and more consistent. Right now you've got strokes that vary letter-by-letter, some corners are more rounded than others, etc.. It looks a little too hand-drawn, and could work well if it was just cleaned up.
Another thing to consider with this is how arching the logo up over the rear wheel well is going to work on the passenger's side. To me this is going to be the hardest part of this wrap, to pull that off. On the other side it's going to read down hill, which almost never looks right. And if you just plop the logo as-is on the other side the italicized letters are going to point to the ground.
If it were me, I'd forget the wrap design for now and focus on getting the logo dialed in. Your concept is not bad, but the execution missed the mark. If you're struggling with it, nothing wrong with that, hire someone who specializes in that style and let them do it for you, it'll be a very wise investment. When the logo is spot on, then design the wrap around it. Right now you're trying to design the logo around the lines of the vehicle and that's a no-no.
