There are several roof options:
24S is a blue lexan removable panel, by itself, 650.00
64S is a gold lexan removable panel, by itself, 650.00

C2L is DUAL removable panels. One is painted body color, and the other is blue or gold. 950.00

If you have two top listings, you probably have C2L and 24S

I don't believe that is what the Window Sticker is talking about... It reads "Blue Removable Roof Panels"        No Charge. The standard Targa roof is listed seperately. Anyone else have an idea?

Do you have the build sheet? If not look under the console lid and your options should be listed there and then you can use the codes DaveP gave. 

I wonder if it's a misprint? "Blue" should be "DUAL"? But then they shouldn't be No Charge.

First, does your car HAVE dual roof panels? Look at the SPID under the console door. C2L, 24S, 64S are roof options for coupe.
Then, what charges ARE on the window sticker? If DUAL = 950, if lexan-only = 650, if painted = No Charge.

From there  you should be able to figure out if there's a mistake in transcription, or calculating line items. Look at the SPID or Build Sheet. Then make those options 'fit' the window sticker.

I think there's a mistake in transcription. or interpretation.
