I do think Bordeaux fared best out of any region in 2003 in Europe. The wines are so sturdy already. I think some Chateaux made great wines that year like Montrose and Pontet Canet. But many have that roasted quality. I wouldn't buy blind. I you go to a tasting of them and like a few then great, but proceed with caution.
I have a hard time believing they are falling apart like some articles have recently stated. I don't think many were great to begin with and they are now just awkward. In 20 years they will at least have more secondary characteristics making them more interesting.
