Hi Bob,

Welcome to the forum! Great to see another E46 owner joining us. We're still building up the community, but we're eager to help

Why don't you share some photos of your 323ci? Always cool to see another BMW in the family. With 72,200 miles on the clock, I bet you've got some stories to tell.

Looking forward to hearing more about your ride!
