Yeah, the 323 (VPW) worked on the PT Cruiser and the 322 (ISO) worked on,a Citroen Xara and a Peugeot 307. The 327 (multi) works on the Xfire if you select the fast init ISO protocol (No. 5 I think it was).
Edit: Just thought I better add that although I got the 327 to communicate with the car it was with a terminal emulator only. I couldn't connect to the car using the free Scantool.net software - I always got an initialization error irrespective of whether the engine was running or not.
