I currently am leasing a 2004 Audi A6 2.7T. The lease is up in October. Since the A6 equiped the way I want it is now $55,000( was $45,000 last time) I am probably going to buy either the Sonata or the Azera. I have been unable to really find comparisons. I do like the looks of the Azera more. are the seats more comfortable than the Sonata(many reviews say the Sonata seats are bad on long drives).I know the gas milage will be less but probably no worse than my A6.I am more into luxury than sportyness.Like a real quite car with no rattles. Also I have heard that the servicing required is frequent and costly. I have been unable to find the reccommended services anywhere.what kind of combined gas milage are you getting? does this car corner any better than the Sonata?Are the radio controls easier to reach?
