Hello. I have one post in the 5 Series forum, but since this is the newbie forum, I wanted to come say hello and thank you all for all the valuble information here. I only recently began to consider buying a BMW, and so far I am leaning strongly towards the 530i, somewhere around 2000 to 2002. Great looking car inside and out. I do have a few questions. I keep seeing pictures and two things keep catching my eye. First, on the drivers side door (inside) there is something that says M123. What is this? Second, on the front and back bumpers there is what looks like a 2 x 2 inch or so square. Looks like a cover over something. What is that? Well, can't wait to find MY 530i. It's out there somewhere waiting for me to drive it. [driving2] .
