If You Want To Unlock Most Of The Cars Like Samatha's Car Or Eddi's 
Car Fast Just choose A 5 Star Reputation Car And Play In Drift And 
Make It 10 Laps It Will Give You More Styling Points Than Drag Or 
Circute Or Sprint And Also It Unlocks Vinly And Some Body Parts....Enjoy

If ur car isn't gaining speed then at the evolution mode go to 
the garage and select a car. then go to parts and buy new and 
advanced parts (i.e. buy big bore throttle body,high performance 
exaust system etc. and replace them with standard throttle body,
standard exaust system and so on). u can also buy other many advanced 
parts and then come back and go to the car setup and install those 
new parts that u have bought and take part in races. ur car gains a 
lot of speed.u can earn lots of dollars.have fun!
