I currently have an AP-SUB-003 for 08-12 WRX for sale. I currently have the everything except the box and CD that came with it. You are not going to need the CD since you can download the software directly from the COBB website. I also had it recently sent to COBB to have the screen replaced and they also checked all the diagnostics on it as well.
