From where does top gear get their car from?

You see all these new racing cars on their tracks, you see them doing racing challenges in the expensive cars(Bugatti, Pagani etc), do they buy the cars, rent them or borrow them. Sometimes they even crash expensive cars, what about it??|||they are 'press cars' loaned to them by car manufacturers to test. the same car will be handed around several motoring journalists.|||I love Top Gear! But yeah the cars are loaned to them by the car manufacturers. I'm sure the companies must know there is always a possibility of the car getting ruined, especially when The Stig knows the car can go a little bit faster.
