I had my tires replaced last year when I was told I just don't know which version of rim it is regular or the darker color. Its hard to tell from web pix and buying parts on ebay seems risky.
How can you find out - does the vin help?
Sure, through up your vin, I'll go on EPC and get the part number details for you
But again, if it's just a minor bend just have a good wheel shop straighten and color match the bent wheel.
It's no big deal, they do it all the time. Unless it's structurally compromised I would get it straightened and repainted, they can match the color.
I just looked on EPC using a generic CLK500 w209, the vin would be more specific.
But the EPC extract, copy and pasted below shows the two color types for that wheel, which one is darker is just a guess, I would think Titanium would be darker than Sterling Silver-- your vin will be more accurate, but might be the same, (ES2 is the color code)
