The Sonatas are really nice for what you pay. They depreciate so fucking fast you can get a loaded 2007 or 2008 Limited for $15,000, easily. They're quiet and decently quick for what they are., plus come with a bunch of safety features standard.
They ride on the softer side but are still sportier than a Camry, but that's not saying much.
For $15,000 you could also get a Civic Si sedan/coupe or even an older TSX.
But the 100,000 mile warranty isn't transferable. Only come with new cars.
