Which dealer was it? (PM me if you prefer not to name them publicly)
I'm also in the Buffalo area (Williamsville), and have had two Sonatas over the last few years. Bought a 2012 SE in June 2011 on a three year lease while still living near Cincinnati. Moved to Buffalo in spring of '12, and the Sonata did well in the snow with 18-inch wheels the first year, but by the next winter the tread was quite worn down and the tires needed to be replaced. Other than routine maintenance, the car was trouble free the entire three years, and got great mileage.
Last spring I turned it in off lease and picked up a 2014 Sonata GLS w/ preferred package that added heated seats, backup camera, and a few other items that I can't recall, on another three year lease. That was from a dealer here in Buffalo, and I dealt with the internet sales manager. He knew the product well, and was fine to work with. Ended up with a zero down 12K/yr. lease for $228/month.
