'ello John, want a new motor?

I was looking for cars on the generally excellent autotrader website, which seems to work OK even though it keeps telling me I need 'additional plugins'. Following a link for a particular car I was taken to the website of Arthur Haslam Motoring - and got this ...

And do you know what Arthur? I really was looking for a car. And the car you had was of interest ... but there were others on sites that downloaded on my PC.

What is the opposite of kerr-ching?
