Top Gear, Series 5

[During the £1500 Porsche challenge]

Jeremy:
What is the next challenge?

James:
You've got to spend the change from your £1500 budget...

Jeremy:
Yeah..?

James:
And with it, you've got to improve your car as much as possible and have it judged by an independent adjudicator who is from the Porsche owner's club.

Richard:
Yeah, so you can spend all of the money from your £1500 that you didn't spend on your car... on your car.

Jeremy:
How much did you spend?

Richard:
I spent £750 on my car, so I've got £750 to spend on improving it.

James:
I spent £900 on my car which gives me £600 to spend in improving it.

Richard:
How much did you spend?

Jeremy:
[mumbling] 1500

Richard:
Sorry?

Jeremy:
1500

Richard:
So you've got nothing to spend on improving it.
