Spartan I have a base model 2015 Sonata that is a surprisingly wonderful car. I thought about suggesting the Genesis as a luxury option in this thread too, but it seemed like the tastes were for the German stuff.
Even a loaded late model Sonata with the "Limited" trim and the 2.0L turbo engine could be a great option for an inexpensive luxury-type vehicle.
I used to fancy high end cars, but now I can't imagine wanting more than a Sonata with a few more upgrades than mine. It's a great car - especially for the price.
