Pro Street Veyron

I read about people who have released the Bugatti Veyron on the need for speed pro street. There are even videos with people using the car: youtube.com. I have a Playstation 3 and want to unlock these cars. I looked on the PlayStation Store and they have no downloads for it. I'm beginning to wonder if it's because I live in the United Kingdom. Has anyone successfully downloaded the expansion and, if yes you are in the United Kingdom. Plus if anyone knows how to get this download please explain how.
Thank you in advance
