I make a few trips to Miami several times a year and its always nothing short of a full blown car show there at all hours of the day.
I was there 3 weeks ago and saw some really nice cars as usual. Unfortunately I was there for buisness and didnt have my digicam all the time but I did manage to get a few snaps.
