I admit I didn't like the 5th gens when they came out but I have warmed up to them. The 6th gens to me look like a spaceship, and I can't tell the front end apart from the 200. I haven't sat in one to see how I like it.
The 3rd and 4th gens to me feel more 'airy' compared to the 5th. I liked the styling of the 3rd gens since they came out, and I also like the late 4th gen styling pretty well. I also really liked the interior of the 3rd gen, back in the day.
