August 2003 i was driving on I-55 in chicago and out of nowhere, this BMW x5 flies past me, or at least i thought it was one. as i caught a glimpse of it, i noticed it was running on 20's, not something standard or an option for the x5, had four chrome exhaust tips, and side and rear molding. I looked at the model number and saw that it said M52. Did BMW really make an x5 with a 5.2 liter engine and M tuning? I've never read anything about this before, and that car was fast and loud. The engine sound reminded me of an FX 45.
