Hi r80rt,
I have the same bags in black on my C5 maroon the look great, I've had them on for the loast 1 1/2 years. The only problem I took them off for the first time the other day to clean my bike after a week long bike ride and they have rubbed of a lot of paint right down to bare metal on the bottom strut. I've touched up the paint but I haven't put the bags back yet till I get some plastic/rubber tubing on the strut to protect. I hope you will do the same, don't want to damage the paint work like mine.
