I had a regular, El Cheapo, six cylinder Gremlin without these options, but would have loved to had A/C, at least. A friend had a Gremlin X with all of the goodies on it and it really made it nice to ride in, especially in heat, traffic and parking.
Man, you've got a wife that will hang out with you at the junk yard? You wanna get rid of her? I'll swap you a really good cook for her! (Just kidding and don't tell my wife!)
