How does the Nissan Sunny perform on long-distance highways, i want to use it to commute?

The Sunny is excellent in fuel consumption, but on highways, the insulation isn’t that great, and you can feel the wind coming in, especially when the speed is above 120 km/h.

I tried it on a trip from Riyadh to Jeddah; it's comfortable to drive, but you need to be careful when overtaking because the 1.6L engine isn’t very powerful.
