CHASSIS AND ENGINE NUMBERS



Chassis numbers as from model 1972

The illustrations below show the locations of the chassis

and engine numbers. To ensure correct identification in

the case of a particular car or engine, these numbers,to-

gether with the mileage, must always be quoted in warranty

claims, etc. If a service engine is fitted in a car, the number

of the original engine must, without fail, be stamped in the

appropriate place. This is of the utmost importance if cus-

tams difficulties are to be avoided in the event that the car

is subsequently used in a country other than that of regis-

tration.

As from model 1972, the chassis number consists of

eleven digits. Explanation of

the

digits is shown in the

following example:
