If you look at the Elantra Sport as an outright sports sedan, it's not going to impress much.
but if you look at it as a daily driver first, it is great. It drives well, has about 200hp on tap, not boring like a regular sedan and has decent in-car features as well. DCT transmission is good, not anywhere near as advanced as the DSGs are but is still miles better than a CVT or Auto. Power is acceptably good as well. Just don't expect it to feel as refined as a new Civic, it is not.
The only big gripe is the inside. If you can take the cheap-ish eye-blinding red seats and accents than you're good to go. To be honest, in my 1 week drive in the car, i hardly took notice of the red accents much. I heard it's a zipped-on seat sleeve, so who knows, perhaps it can be removed
