Apparently you car was made in Antwerp, Belgium. Just have to post a photo as the styling changed year to year back then.
GM closed the assembly plant in Antwerp in May of 2010 as part of it's bankruptcy. They had been making Opel cars there prior to shutting down the line. I was going to suggest a pilgrimage to look at were your car was "born", but I'm afraid by now even the building will be gone so I expect all you would see is will be just a fenced off vacant lot.
