I'll add that it might not have the brand cache that the three pointed star does (which doesn't mean sh!t to me), but the Q50 Red Sport offers WAY more bang for your buck at a much lower price point. Same goes for the IS350.
Yes, the Q50 Red Sport is awesome bang for the buck, but it compares more to the C-Class. The Q70/Q70L is more comparable to the E-Class, but the Q70 is in need of updating.
As much as I do like the styling and execution of the E-Class, I would still have to seriously consider the Lexus GS and Genesis G80. I would even give the next gen BMW 5-series a serious look.
This got me thinking of things that Mercedes can get away with that Hyundai would be CRUCIFIED for:
1) Here's our brand new Genesis G80 midsize luxury sedan, now standard with a 2.0 Turbo!
2) Here's our brand new Genesis G80 midsize luxury sedan, now standard with rich Corinthian vinyl seats!
3) Buy our brand new Genesis G80 luxury sedan and enjoy the added character and excitement of consistently wonky electronics!
Be real now - wouldn't we be witnessing a chorus of laughing and finger pointing and declarations about how Hyundai doesn't understand the luxury segment?
