If you pm me your vin and email I'll see what I can dig up in gm's systemYes I bought mine used. Its a red 6speed manual. I was told by GM it was first sold in Sept 2012 . Carfax shows it was registered months after. So my thought is that GM had it in some showroom before it was actually sold to the original buyer.
I probably need to order the build sheet.
Also, look for OAR and WDO on the RPO sticker, in the spare tire well. If those are there, you have a Captured Test Fleet vehicle.
If you have the Window Sticker and it shows shipped to Orion Assembly Plant or GM HQ in Detroit, you have a Captured Test Fleet vehicle.
I am predicting you have a CTF.
