You may sue in small claims court for that if you wish. But you won’t get anything for “shame” or “hassle” as neither of those things are legally recognized damages. Nor will you get anything for the time you have spend going to court over this, either. What you would be entitled to get is the reasonable cost of removing the sticker. So you might get the $10-$30 you spend for that, plus reimbursement for the court filing fee and fee for serving the complaint on the HOA. That’s it. Your posts are becoming more strident on this as we go along, and I suspect that the more you are thinking about the more irritated you are getting. You are reaching a point here of making a mountain out of a molehill. I doubt the HOA really intended to do any harm to your vehicle. I don't see this as quite the same as vandalism. Rather, it strikes me as far more likely that it is simply negligence — they may not be aware of how difficult that notice is remove.
In any event, I suggest that before you go running off the courthouse that you try to amicably work this out with the HOA. Address the issue of the notice being hard to remove and that you needed to pay someone to get it off, but avoid casting about terms like vandalism when you talk with them. Human nature being what it is, if you go in there all angry and accusing them of committing crimes like vandalism they will themselves tend to get angry and defensive, and be far less likely to want to help resolve it. It is in your interest to preserve a reasonably good relationship with the HOA board and staff if you can, since having a good relationship can make working out future problems that may be even more serious much easier. If you develop an antagonistic relationship with them what you will get is conflict after conflict with the HOA. I have seen that happen in HOAs, and it can make the homeowner miserable. There are times you need to go to court to deal with serious problems with the HOA, but IMO this is not one of those instances.
