Okay so i went and checked it out today.
Exterior:
No doubt it looks awesome from every angle in exterior. Looks much wider and longer than civic or grande, like sonata. Paint quality and materials are great. One different thing is Drls stay off until you disengage parking brake.
Interior:
Rear leg space is better than previous elantra and matches civic grande now. However rear door cards don’t have good materials. Hard plastic. No rear armrest. Rear ac vents dont have any dial. Hump is there in the middle.
Driving seat is a different story. I would rate it better than sonata. Searing position is lower thsn prev elantra. Everything wraps around you and I just loved the comfort. Pretty wide. Steering is beautiful. Leather and dashboard is premium unlike rear seats.
It still costs 20 lakhs cheaper than sonata. If you mostly drive yourself buy elantra. If you want to be chauffeured around get a sonata or civic.
