First thing you need do is learn everything possible regarding the ordinance they are charging you against, and research all prior cases citing the same ordinance. Goal here is to understand WHAT you're being charged with, research how judges ruled on similar cases and if there were any legal precedents set that you can work in your favor. Depending on how sharp & resourceful you are, you can do most of this without a lawyer - this stuff is largely on the public record. My best guess is this ordinance is all about $ and collecting registration fees.

For example does the "Inoperative/Unlicensed Vehicles" language in the 106-54 ordinance you've been cited for mean it's a violation for the cars to be both "inoperative" AND "unlicensed", or is it "inoperative" OR "unlicensed"? How the law is written could possibly reduce the scope of the problem that you have to deal with...

Another thing worth looking into is seeing if you can get a variance or waiver on your property zoning - e.g., getting them to allow you to effectively re-zone your property from "estate residential" to something else (e.g., used car dealership lot?) that would allow you to keep the cars. That might have unintended consequences though, such as changing the value of your property or jacking up your taxes.

Edit: To pile on to what Gunny suggested, the definition of the word "enclosed" in the ordinance could be key. If there is no clear definition of "enclosed", you might have legal grounds to cover the cars with tarps, or putting up a fence that blocks the view. Of course, there may be other zoning & permit issues associated with putting up fencing, so don't forget to look into that before taking action.
