Hyundai Genesis 3.8 Reviews
My 2012 Genesis 3.8 sedan is by far the best vehicle I have owned, I opted for the Technology package. This car is a dream to drive, the optional (LDWS) lane departure warning system is useless, it is suppossed to warn you if you drift into other lanes but it only gives a LOW beep which you can't hear if you have the radio on. The Smart Cruise is a very nice feature. The Lexicon stereo is the BEST on the market, although the integrated nav system is not as user friendly.the HID headlight are now a dealbreaker for me (I must have them)the leather is soft and very high grade, the drivers seat also has a cooling function (nice). Overall this is a very sound car at a great price.
I HAVE THE TECH SETUP. THIS CAR IS A WONDER OF TECHNOLOGY.A BIG BANG FOR A GOOD PRICE. THE ONLY COMPLAINT I HAD WAS WITH THE ORIGINAL TIRES.THE RIDE WAS VERY HARD. I HAVE REPLACED THEM WITH UPGRADED TIRES THIS SOLVED THAT PROBLEM
