I have an Elantra.
I had the same concern with you which one to buy from Accent or Elantra.
I think that the Tax or Insurance premium has little
difference. I’m not sure. You may ask insu broker.
Basically, Elantra is much better in value, ride feel, size, power… than Accent. The price is not that much more expensive than Accent if you add the same option to Accent as that of Elantra such as power window.
So I recommend Elantra strongly if you use the car
more than a few years.
Good luck.
