Sorry to go against the grain here folks, but your dealer if full of it!!! His license to sell Cobras should be revoked for feeding you such blatantly BAD information!

You DO want, and WILL use your heater and defroster wherever you live.

And if you are expecting your headers to keep you warm, you haven't properly coated your headers, or insulated your footwells.

Lastly, if you live in a State where your car needs a safety inspection every year (not emissions, just safety), you will need working wipers, and heater/defroster to pass.

Yes, there are options in registering your car as a classic, or antique where even safety is not required. Now, you're all smart guys (and gals), right. Get into a fender bender with no safety and the opposition will eat you for breakfast in court. So, even if you don't need it, get it (annual safety) anyway. And put a heater/defroster, and wipers in it.
