I can't say enough good about both our Hyundais. My 06 Sonata GLS is a very fine car indeed, and at 46,000 km, it still drives like new. None of the rumored grunts and groans some have reported around the rear suspension. It's very roomy, drives well, and gets good mileage.
I would buy another one just like it if I were in the market. What I like most about Hyundai right now is that they are trying less and less to copy the competition, but just kinda flying below the radar and offering exceptional value for money. It is pretty tough to argue the value - you may not get the best rated car in the world, but for the money, they really don't feel any different than what they are competing against, except, perhaps for the Mazda 6. But then, all the competition is tough to compare with the 6, imo.
