I wasn't aware of this. The biggest issue I see then are the wheels, I don't think he cares about the emblem. If anything happens, perhaps Ebay might be of assistance or other local markets. I don't have any experience in these special editions, but think that ruling out a potentially good car because it may be hard to obtain a replacement wheel seems odd. In my 14 years of driving, never hit anything with my wheels (knock on wood) and neither has my dad in his 30+. Though, now having said that, I'm sure in 2-months I'll be scouring the net of for a used 2000 ES Millennium wheel .
An auto manufacturer is required to manufacture parts for a period of 7 years, so it could be difficult to get the special replacement wheels that were originally equipped with this model.
