In the US right now, Mustang, Camaro, and Challenger. The Charger's not bad looking either, though I don't know the prices on any of these. I see lots of Corvettes every day too, but they don't really fit your 'affordable' requirement, I think.
Sadly, most everything else is either a truck, SUV, van, or the oh-so-popular "Let's all have the same basic mushed lumpy teardrop shape, but throw on different headlights and grill so we don't look exactly like our competition" option that every single carmaker seems to be doing now.
