I hope you mean no new sticker and that the old sticker is still in the window. Unless the sticker has expired, they are not suppose to remove the sticker until you pass. If they do remove it, and you fail, then they should give you a temp sticker.
Welcome. I agree, get it fixed first. Drive it some. If you still want to find a different one, then go for it; at least it will be easier to sell all fixed up.
