Yes, you're right salva72, they look like the 18" silver 15 spoke alloys (C54S).
I know a lot of folks on here like their really big rims and wouldn't consider anything below a 22", but those silver spoke wheels look surprisingly good on this Sapphire Blue car, nice contrast, but then I don't mind seeing some tyre-wall rubber on wheels . . . and loads of rubber gives plenty of protection from kerbing, in fact you'd probably be hard-pressed to find a kerb high enough to do these any damage, so no need for alloy wheel insurance either! . . oh, and I bet they soak up the road-ruts very nicely too . . . so, a win win!
Only practical down-side I can think of is when trying to clean them with a cloth or sponge, all those fiddly spokes to get around! . . . that's what pressure washers are for tho' . .
(. . oops, you just beat me to it JefF, didn't see your post came in a few mins before mine . .
