Just happened to see this again today and a possible cheap and easy
solution came to mind. I would first consult with an attorney, and
have him send the assoc a letter outlining your position that the space
is yours and cannot be limited by the assoc. If that doesn't work,
then, run this idea by your attorney:

Refuse to give them the keys or move the car for trash removal. The
assoc really only has 2 choices. They can fine you, they can have the
car towed, or both. Let them tow it/fine you, pay whatever it takes
to get the car back, then file suit in small claims court, where you
can get it heard without paying for a lawyer. . That will force them
into court with very little expense on your part. With the condo
Master Deed, Bylaws and your title in hand, you will almost certainly
win. That may be enough to convince the assoc they are wrong and be
the end of it.

However, they could either do a legal manuver to move it from small
claims before it;s heard or appeal afterwards. Still, it is one way to
get a possible decision in your favor quickly, with little cost, that
might settle the matter. After having them tow it once or twice, I
would then move the car myself from then on until you get to court to
avoid piling up fees on the small chance you will lose
