User Experience: difference between the two Model-S’s

A user test: a Dutch Master in Amsterdam tested the older Model S Stainless Steel and a new Model S Black

"The two models are technically identical. The difference is of course the color. The magical 'silver' of the original RP3 has been replaced by black coated aluminium. The other big difference is the new air intake system with aerodynamic grille shape, which makes significantly less noise. That makes a difference in the small attic room."
