Midnight Races?

Hi

What are midnight races? and what do you get from them

When you have done a certain amount of street races you get to do a midnight race and if you win you get to keep the other guys car

Is it a race against a computer player or another online player

its a AI drivatar , its all in singleplayer

you get them when you race other drivatars in a head the head race by challenging them and winning x number of them.

Thankyou for all the help
