When I think of companies that make cheapness cool I think of IKEA, Primark, Ryanair and Fiat, not Apple and Porsche. The Macbook Neo and the Porsche 968 are cheap only compared to other products by the same brand and they are designed not to cannibalize those other products.
Not sure how a company like Primark that is known for using slave labour is "cool" or who would see it that way. Everyone I've ever heard talk about Primark went there solely for the price.
Zara might be a better example (though not much better in practices).
