I purchased a
2014 E350 for my daughter and you want to compare it to a Hyundai?! Okay they both have 4 doors, 4 wheels, trunk and a hood .. end of comparison. Once you get behind the wheel and drive it out the parking lot you'll quickly realize the differences, not to mention if you have the misfortune of an accident.
The Hyundai's are fine cars, but so are Porsche, Bentley, Rolls, Lamborghini, Bugatti, etc and comparing them is nearly ridiculousness and each has its markets. I recall a review on my old 500SL and them complaining it was 15 MPG; like spending (then) nearly a $100K for a convertible (2nd car) sports car I or anyone gives a crap!
