I'm happy you like your new Hyundai Elantra OP. Yes, a 4-door sedan with its better ride and handling is a better choice when SUV features aren't required. I've never driven one myself, but I've ridden as a passenger, and it was nicely appointed and had a good ride feel.
10 year warranty? That's pretty amazing. My Corolla came with a 3 year bumper to bumper warranty, even included things like light bulbs. Toyota paid for all repairs, parts and labor, except for routine maintenance (oil & filter changes and the like) for 3 years. I can't see how Hyundai could do a 10 year bumper to bumper warranty like that, it must have some limits. Just curious, what limits does it have?
Numbers used for the speed rather than a sweeping needle? Reminds me of a story, years ago when micro-computers first appeared a coworker and I were blue-skying how they might be used in a car design. We came up right away with the idea of using a digital display for the speed. We were feeling all smart and sassy about this great idea, how accurate it would be, etc etc , until the co-worker told it to his wife. She immediately replied "That's no good, it's easier to glance at a needle to judge your speed and how it is changing from glance to glance than to read digits". We got to thinking about what she said, decided she was right, so we gave up on the digital car design ideas and went back to work on what we were supposed to be doing ... lol ..
Edit: I did a walk-about on Auto Row a few weeks ago, visiting all the dealerships parts department to see how accommodating they were and how they treated me overall. The Hyundai dealership was one of the better ones. The best was the Nissan, followed by Toyota. Worst, Mercedes.
