One more note, from what I've researched, it appears that production stopped in Graz before the convertible was produced. Some sources I've seen say it was just early PT Cruisers that were built in Austria, but it was costing Chrysler an extra $2300 per car, since most of the parts were sourced from North America. Chrysler switched production to add more Voyagers, since they used more local parts, so the cost benefit was better.

This source says only 2001-02 were made in Graz.

Wikicars also says just 2002 models.
