I have completed nfs Most wanted all levels many times and here is a trick that you can use to play nfs Most Wanted any level with any car you want. This is very much useful if you have just started playing the game or are in the middle of the career somewhere and want a sneak peak or get a little taste about what is inside at the top levels of the game. By-the-way, I always play using Lamborghini Gallardo.
