Thanks for the thread. Interesting in learning more.

Maybe a 4.8is specific discussion thread/registry as well?

My 4.6is shows a build date of August 29, 2003, making it one of the very last 4.6is built. It only has 50,000 miles. It is sapphire black with black interior with titanium trim. I have the build sheet from BMW so if anyone has any questions about what makes a 4.6is, maybe I can answer your question.....
