1970 Mercury Cougar XR7 Houndstooth. Limited to the XR7 and offered for a single year with either a black and white or a brown houndstooth pattern vinyl top and interior. Not sure how they break down but the brown seems to be more common, while I think the black and white is more attractive.

The venerable Fiat Panda 141A (1986-2003) NEVER had air conditioning in most of the markets it was sold in, except for Japan of all places; this is a later Selecta (with an ECVT, another rare option outside of that country) model from the late '90s equipped with AC:

I must imagine how perfomance would be affected, since the fastest OG Panda tops out at 54hp (!) from a 1.1l 4 cylinder .
