A brand new car with 15 miles on the clock and £4,000 off the list price. It sounds like a mistake in your favour. Buying an ex-demo or pre-registered car can be a very good deal, but the discount exists for reasons, and some of those reasons cost you money later.
What Pre-Registered Actually Means
Manufacturers set dealers sales targets. When a dealer is a few cars short at the end of a quarter, it registers new cars in its own name to count them as sold. Those cars then go on sale as used, with delivery miles and a new car smell.
Mechanically you are buying a new car. On paper you are buying a used one, with one previous keeper on the V5C. That second point matters when you sell, because buyers see two keepers instead of one.
What an Ex-Demo Car Is
An ex-demonstrator is different. The dealer has used it for test drives, as a courtesy car or as staff transport. It will usually have between 1,000 and 6,000 miles on it, and those miles were covered by many different drivers.
Some were careful. Some were trying a hot hatch for the first time on a dual carriageway. You cannot tell which from the mileage alone, so you inspect for it.
Four Things to Check Before Buying
1. The first registration date
The manufacturer warranty usually starts on the day the car was first registered, not the day you collect it. A pre-registered car that sat unsold for eight months has burned eight months of a three year warranty. The same applies to roadside cover and any service plan tied to the registration.
Find the date on the V5C, or in the free vehicle details on our results page. Then work out how much cover you are actually getting.
2. The first MOT date
Cars need their first MOT three years after first registration, not three years after you buy them. A car registered 18 months before you bought it needs an MOT 18 months later. Our guide on driving without an MOT covers why missing that date matters.
3. Signs of test drive wear
On an ex-demo car look for:
- kerbed alloy wheels
- worn or glazed brake discs for the mileage
- a clutch biting high on a manual, which our guide to signs of a failing clutch explains
- scuffs on the driver's seat bolster and sill
- stone chips on the front from motorway runs
4. The history
Pre-registered cars rarely have a history problem. Ex-demos occasionally do. Courtesy cars get damaged and repaired, and a repaired car is still worth less than one that was never hit. A Full Report shows write-off records, keeper history and any outstanding finance from the dealer's own stock funding.
How to Negotiate
Treat the advertised discount as the starting point, not the deal:
- point to the warranty months already used
- point to the extra keeper on the logbook
- ask for the first service, mats or a warranty extension if the price will not move
- compare against a new car with finance offers, which can sometimes beat a pre-registered price on the monthly payment
Dealers registered these cars to hit a number. The car is now costing them money every week it sits there.
When It Is a Bad Deal
Walk away if:
- the warranty has less than two years left and the discount is small
- an ex-demo shows more wear than its mileage explains
- the dealer cannot say how the car was used
- the price is close to what a new car costs with a dealer contribution

FAQ
What is a pre-registered car?
A new car the dealer or manufacturer has registered in its own name, usually to hit a sales target, then sells on with delivery mileage. It is technically used, so it shows one previous keeper, but it has barely been driven.
What is an ex-demo car?
A car the dealer has used for test drives and as staff transport. It typically has a few thousand miles on it and has been driven by many different people, some of them hard.
Does the warranty start from when I buy it?
No. The manufacturer warranty normally starts on the date the car was first registered, not the date you buy it. A pre-registered car that sat on a forecourt for six months has already used six months of its cover.
Are ex-demo cars worth buying?
Often, if the discount reflects the mileage and the use. Check the first registration date, ask how it was used and inspect for test drive wear such as kerbed wheels, clutch wear on manuals and scuffed interiors.
Can I negotiate on a pre-registered car?
Yes. Dealers registered the car to meet a target, so it is now stock they need to move. Use the time already lost from the warranty and the extra keeper on the logbook as reasons for a lower price.
