I've got a large collection of those green microfiber knobby mitts from Autozone (though they're getting harder to find); I typically have used these with a rinseless wash after rinsing the car down with a power washer (I'll do a foam soak first if there's dirt from driving in the rain, etc).
However, I'm trying this new sponge I found from Esoteric Car Care; they're imported from Japan (even the packaging is completely in Japanese). Initially I was skeptical since the first time I wrung one out, I tore a "tooth" off, but after figuring out the best way to handle it, I've gotta say I'm impressed.
They're very soft but hold a lot of liquid; you don't apply any pressure, just let the weight of the sponge and the rinseless wash create the pressure. You would NOT want to use this to remove any dirt/grime/bugs etc; you'll still want to use the knobby mitt for that, but for purposes of a quick "slick up" wash, these are great. They're not cheap, but you certainly won't introduce any swirls or marring with them either.
My previous Challenger was Pitch Black, so unless you want photos to prove my bonafides, take my word for it that I know what it takes to avoid swirls...
