How our prices are calculated &
why it works
We aim to provide the most useable prices possible for used car buyers and
To make them accurate we base all prices on real cars in the market today.
As you will see when looking at a price, we are continually monitoring hundreds
of thousands of cars.
To make them really practical and useable in the modern car-buying world, we
give you three prices:
- The top price is what we expect good quality dealers to charge. You
can haggle a small discount from this price.
- The best price is the lowest a savvy and reputable seller (who is
not in a rush) would expect to sell for.
- Anything in the middle is a fair price and deal for both sides.
What does 'confidence level' mean?
When you look for a price on this website, our system searches the latest data
available. Sometimes this means there are not as many examples of the car you
are looking for available as we would like, to ensure a really accurate price.
We have therefore set five levels of confidence:
All the prices are based on real cars, so they reflect what is happening in
the market. The 'excellent' prices are based on a large sample of cars and so
give a more accurate price than the 'poor' prices which are based on a small
sample of cars.
With some more specilaist cars you will only ever get a small sample of cars.
So you should not worry about a 'poor' rating but proceed with caution as the car you
are about to buy may be rare and prices may be volatile. Visiting several cars and comparing
them for price vs. quality is usually the final answer.
Year and 'Number plate premium'
New number plates affect the value of a new car significantly. They have much
less impact on used cars than the engine, specification and mileage. For example
a car with a '57' number plate that has completed notably higher mileage than
an otherwise identical car with an '07' number plate will be on the market for
All prices in this guide are based on the following assumptions about the vehicle's
Cars with mileage of 0 - 30,000 will have hardly any wear.
Cars with mileage of 30,000 - 60,000 can be expected to have some minor
scuffs on plastic and very slight creasing or fraying on seat squabs. Bodywork
should be in very good condition, with only very minor stone chips or occasional
fine scratches on the main panels.
Cars with mileage of 60,000 - 90,0000 will have more scuffing and fabric
creases or fraying. Seats may have begun to sag slightly. The ceiling of the
car and light trim may also be slightly dirty or marked. Some plastics will
be a little shiny in high wear places, such as control stalks, gearshift and
steering wheel. Pedal rubbers will be showing signs of wear. Load areas may
have some scratches. Bodywork should be in good condition, with some stone chips
on the front of the car and some minor fine scratches on other panels. There
may be the odd very small dent (less than 160mm2 ).
Cars with mileage of over 90,000 will have very shiny gearshifts, control
stalks and steering wheels, and light fabrics will be marked. Some seat squabs
and backrests will be creased, sagging and frayed. Pedal rubbers will be significantly
worn. Load areas will be scratched. Bodywork may have quite a few stone chips
on the front, a few scratches in other panels and one or two very small dents
(less than 160mm2 ).
Damaged or Abused Cars
No car, of any age should be valued using this guide book if it has visible
rust, major dents, broken controls, badly torn or stained interiors. With cars
in this kind of condition, buyers are advised to obtain quotes for repair and
discount the guide price accordingly.
All prices assume that cars under 5 years old have full service history and
older cars have at least 80% of their standard services and all major services
or key component replacements (e.g. Cam belts) completed and recorded.
Operational car with M.O.T.
All prices in this guide assume that the car, engine and all mechanical parts
work. All prices assume that the car has a valid M.O.T.
