Nice, and congratulations! I've had my 2000 528i for nearly 7 years now, and love it. It is, without exception, the best driving car I've ever owned. Good news that your car had the cooling system improved, and that there is no front shimmy. Cooling and suspension seem to be those nagging items that I've had repaired over the years. The suspension is wonderful, but it is a little high-strung and does wear. Looks like your car has had both refreshed at some point.
Because I have not posted a picture of my car in quite some time, I offer two here to see who else is willing to post theirs. It's had a new paint job in 2010, and some after-market wheels since 2009 (18"). On the latter, I found that, in my opinion, anything larger just didn't look right. I kept the colour original - Cosmo Black. One more thing - yes - that is a bagpipe decal on the rear window.
