The current Accord coupe is one of the better mainstream Asian designs in a while. The sedan, not so much.
My list:
1. Malibu - I know you'll probably think I'm just GM humping, but I think they are the most handsome mainstream sedan out there. I'll take an LTZ in black with the Black/Brick two tone interior please.
2. Milan - I liked the previous one and I like the new one.
3. Aura - Not as visually appealing as the Malibu, but not bad.
4. Fusion - I like the new one better than the previous, but the aesthetic just doesn't grab me like the Malibu and Milan.
5. Legacy - Finally an attractive Subi. I've long respected Subarus as vehicles but I just couldn't get into the styling.
6. Impala - Big car feel for not a lot of money. For those wanting a more "classic" feel without going all out and getting a Grand Marquis, this would be a good old reliable. I happen to like the styling, but wish it would get the new Chevy nose.
7. Sonata/Optima - Fine as an appliance. Mildly more interesting than a Camry simply because it's not a Camry. I'd never buy one.
8. Mazda 6 - The car itself is fine, but there just seems to be something missing in the exterior design. I can't put my finger on it, but something just seems off.
9. Passat - The design is tired but not bad. They've been milking that Passat roofline for about as long as they're going to be able to. Seeing plenty of Skodas in person, the Passat reminds me of them.
10. Accord - The exterior is just off. Coupe is nice though.
11. Camry - Very tired. There are much more solid platforms out there.
12. G6 - Never appealed to me. Interior completely sub-par.
13 Altima - Ditto G6 without the benefit of being a domestic.
14. Avenger - A slightly more attractive Sebring
15. Sebring - A complete basket case. Had a rental in May that should have qualified for Cash for Clunkers right off the lot.
16. Galant - As bad as the Sebring but without any of the "interesting personality".
*Lacrosse is left off because I haven't seen one in person yet. If it's everything it's cracked up to be, it'll probably take the top slot and bump all the others down one.
