Apple's wheels

How can Apple sell 4 pcs of plastic wheels for 700$?

How marketing makes that possible?

Well. It's not marketing. It's a cult.

In 1978 pastor of an apocalyptic cult Jim Jones lead his 900 followers to commit mass suicide by drinking cyanide-laced. In 2018 in South Korea cult founder Shin Ok Ju ordered their followers to beat each other unmercifully to evict the demons.

Cults are influenced by personal feelings and opinions but not facts. Reasons without facts withers rationality. Then you can price the iPhone SE (With a 4.7" retina display and A13 mobile chip and 4K capable cameras and Touch ID and all those other incredible tech features) 300$ cheaper than 4 regular wheels.

Marketing looks for attention to develop trust. You certainly will get attention by beating your followers but you won't earn trust.

Selling 4 wheels for 700$ just does that.
