I think it's the ONLY game I have ever truly beaten the story/campaign in before. Yes it counts as it probably took at least 40 hours of gameplay to do and probably more with all the races it had and my skill level at the time.
Pissed me off though that the beginning of Carbon (the sequel to Most Wanted) you are driving that BMW and it crashes like 4 minutes in and is totaled. You SPEND all of Most Wanted working towards getting the car back and it gets destroyed immediately starting the second game. Lame.
