Just wanted to add my voice to the chorus. I was sorely tempted by the 20s, especially considering how modest the price increment is, assuming you're talking about a 4.8 with the Sport Package. I love the look of the 20s, but I wouldn't love it the first time I bent one of those expensive rims! Not to mention what the 20" run-flats sell for. (Plus I have to deal with snowy roads -- not your worry in NOLA! -- and while the all-season tires on the 19s won't be a substitute for real snows, at least I think they'll do in a pinch.)

Just keep repeating this mantra: The 19s look great... The 19s look great... The 19s look great...
