BUGATTI REPLACEMENT PARTS CATALOGUE
I trust you will find this edition of the Bugatti Replacement Parts Catalogue useful and the identification of the
parts you require easy. Please note that the photographs are an identification tool only and are not to
scale.
The sections and titles used in the previous Parts List have been deliberately adhered to for continuity
purposes and ease of reference.
The catalogue also appears on the Bugatti web-site - www.bugatti.co.uk and is updated regularly when new
items come into stock.
Price lists are not published as costs are too volatile but the Spares Department is always willing to advise
current prices when asked.
Please remember that the Spares Department functions as a service to Club members and can only operate with
your support. Our prices remain competitive in relation to the quality standards that we insist upon from our
suppliers. Stock items are readily available. Over the years much information has been compiled with regard
to a source of supply for many parts which are not listed in the spares catalogue. If you cannot find the parts
you require listed in the catalogue then please do contact us giving full details of your requirements and we will
do our best to assist you.
Refunds
Full refunds will be given on any parts purchased providing the part returned is in the original condition as sold
and the original invoice can be sourced. The maximum term for refunds is two years.
Payment for Purchases of Spares
The Club prefers payment of invoices at the time of despatch. We accept all major debit or credit cards with the
exception of American Express. It is helpful if you quote the card details at the time of placing the order. Cheques
from overseas must be in £Sterling and drawn on a British Bank. Regrettably we can no longer accept
Eurocheques. All cash payments must be in £Sterling.
The Spares Department is open Tuesday, Wednesday and Thursday between 0900 and 1700 hours UK time.
If the Department is closed, please do fax or e-mail your orders or enquiries and I will contact you on reopening.
WOULD NEW CUSTOMERS PLEASE NOTE THAT THE ARTICLES OF ASSOCIATION OF THE BUGATTI
OWNERS’ CLUB LTD ONLY ALLOW THE SALE OF PARTS TO PAID UP MEMBERS OF THE CLUB
