your RPO codes also have 1YY67 = base convertible and WG4 = conversion. Same as mine. That was my question. GS should be 1YG67.
My guess is they all begin life as a base, and then the options are added in the factory. WG4 takes it from a base convertible to a wide-body Grand Sport, and then they add Z16 and Z51 performance options. The RPO sticker is specifically for service parts ordering, everything else (chassis, interior, etc.) it's the same as a base model.. Z06 and ZR1 have aluminum chassis and more carbon fiber bits.

Im new to the c6 scene and learning as i go thanks to this forum and you guys answering my many questions. Hopefully buying it tomorrow.
Here is a listing (description) of what I think is every RPO code for GM vehicles. If you open the PDF and hit the following keyboard keys (for a PC) Ctrl + F it will bring up a find box. Put in the RPO code then click on the forward or back arrow in the find box and it will search the document. Each time you hit the forward arrow it will continue its search. Hope this will help anyone interested.

I think there were only about 350 4LT's for 2011, and the serial numbers were less than 2000 apart.
Edit - I was wrong 385 Coupes were 4LT and 513 Convertibles were 4LT. I thought total % of 4LT was about 2-3%, I guess it's more than double that. Not as close as I thought.
