Um, that's not a 40th.
1. 40th cars are not silver, they are dark cherry (thought it could have been repainted)
2. 40th cars are made in the 2002 year, not 2001.
What makes you think it was 40th? It doesn't say it on the page anywhere. I am almost certain they DID do special edition versions with that same hood in 01 & 02, but I can't find any info anywhere confirming that.
