YOU may not have heard the term, but if you are the type of motorist who chooses to buy a cheap, older car for next to nothing rather than splash out on a new or nearly new one, you could be classed as a follower of "bangernomics".
'Bangernomics' is the title of a book first published in 1993 by British motoring journalist and former used-car salesman James Ruppert.
The book, now long out of print, slowly gained a cult following among motorists determined to spend as little as possible on their motoring.
If you followed the insider buying advice and tips contained in this book, you could buy and run a smart, reliable and perfectly respectable set of wheels that meets all your needs for next to nothing.
Today, the credit crunch has opened up a whole new audience to the concept, and Mr Ruppert has responded by writing a new, updated version entitled 'Bangernomics Bible', which is now available from Amazon.
As well as updating the original, he says the new book has been revised so that the buying principles apply anywhere in the world, not just the UK.
In addition, the quality of older cars has much improved since 1993 and you can get much more car for your money, he says.
Buying a banger also doesn't mean having to sacrifice your green principles, says Mr Ruppert.
"A bangernomics approach means that a car is effectively recycled," he says. "The natural resources and energy used to make a new car is phenomenal, which makes prolonging the useful life of a car and then disposing of it responsibly decidedly green."
