That's too bad, I'm pretty sure all the 2000 models have the redesigned engine regardless of when it was built. Don't feel too bad, you'd rather be safe than sorry. It's unfortunate that you don't live in the USA and I can't just recommend cars because they won't be so easy to find, anyway the 1997-2005 Buick Park Avenues are amazing cars. They got the 3.8L 3800 series V6 both regular and Supercharged one of the greatest modern engines ever made.
