I traded in my 2004 745i on a 2005 645ci. I had a negative equity of $5k on the 745i but it was worth every penny cause the 645ci is just simply awesome. Nowdays, it seems that everyone has a 745 or a 5 series. The 645ci is so unique. I get many looks on the road. In fact, it reminds me of the old 8 series than the 6 series. I got the sports package which I think gives it a totally different attitude. I love this car so much more than that big 745i.
Simplified iDrive; sports package, sirius; just everything
