By the way you would specify for what Cobra your pics are for.
This Alarm für Cobra 11 - Die Autobahnpolizei, TV Series, 1996-2009

Or this one Alarm für Cobra 11 - Einsatz für Team 2, TV Series, 2003-2005

The new cars that robikumpel posted are obviously from Alarm für Cobra 11 - Die Autobahnpolizei (1996-2009). So they can be added as well (there are also a few new Audis )

If I a don't see ANY TV series (except Desperate Housewives and Lost) it isn't so obviously as you say but,.....you win. I'll do it next week and (remember) that the post where robi submited his pics http://forum.imcdb.org/index.ks?page=forum_topic&id=807&index=0 was closed from 22/06/2006
And robi re-opened it in 27/03/2009
That is not the way

@ Vilero: we can say for sure that the cars that robi posted are from Alarm für Cobra 11 - Die Autobahnpolizei: in fact there are some cars newer than 2005 (the last year of Alarm für Cobra 11 - Einsatz für Team 2).
And yes, he would have made a new topic for these new cars, but probably he's new in the site and he doesn't know much of it.
