Interior
The interior layout, fit and finish
The interior of the CLA offers a serious wow factor, especially if you specify it with dual 10.3in screens (as standard, the infotainment screen is that size, but instrumentation is displayed on a 7.0in monitor).
It helps that the graphics are lemon-sharp. And usability is similarly impressive, because the various menus are logically laid out, and you can choose between pressing the onscreen icons, scrolling with responsive touchpads or issuing voice commands to a system that recognises natural speech instead of requiring you to remember specific phrases.
