Walk onto any forecourt or into any car auction and you will hear a language of its own. Dealers talk about stand-ins, PXs, Cat S cars and “a monkey under book”, and customers are left nodding along. This glossary explains the car slang, motor trade jargon and acronyms you are most likely to hear in the UK, in plain English, from A to Z.
Whether you are new to the trade, starting your first used car dealership or buying a car and want to know what the salesperson means, bookmark this page.
Everyday slang for a car
Before the trade terms, here are the most common British slang words for a car itself:
- Motor: a car. “Nice motor.”
- Wheels: your car. “I need some new wheels.”
- Jam jar: Cockney rhyming slang for car.
- Banger: an old, tired or cheap car.
- Runaround: a small, cheap car used for everyday journeys.
- Shed: a car in very poor condition.
- Minter: a car in mint (immaculate) condition.
- Dog: a bad car, either in poor condition or one that will not sell.
Money slang you will hear in the trade
Prices get talked about in slang, especially between traders:
| Slang | Amount |
|---|---|
| Score | £20 |
| Pony | £25 |
| Ton | £100 |
| Monkey | £500 |
| Grand | £1,000 |
So “a monkey under book” means £500 below the trade guide price, and “a ton on top” means £100 more.

Knowing the jargon is the easy part. Knowing the stand-in, days in stock and margin on every car on your forecourt is what keeps a dealership profitable. Haswent’s stock management tracks all three from the moment you add a car by its registration.
