If you just bought your first MG (a first time is always a great experience), first, order a parts catalogue from at least two mg spare parts retailers.
This way, you will be able to compare prices for the same item (and
sometime the same BL or Austin-Rover part number !) with the same
There are many spare parts retailers across Europe and Worldwide, ie :
Moss motors, Moss Europe, The mgb hive, Limora, Heuten, Anglo-Parts,
etc.) As they may have sales or different VAT (or custom taxes) you
will not always find the cheapest item from the same seller. Most of
them have a webshop and you can trust them all even when buying abroad.
They are professionals with good customer services.
An alternate way to search and find MG cars or spares is to browse the web auction sites.
You may certainly know and maybe have already bought throught the most
popular of all : eBay. If not, you should have a look or even register
This way, you might find cars or spares sold by individuals or
companies, and thanks to you personnal eBay profile you will have
access to the Completed listings, showing what is the "market price" on
the item you are looking for (this prevents to bid at silly price).
You may grab bargains while monitoring items you want to bid for. Be
the only bidder and buy at starting price thanks to email alerts on new
items from "your favorite searches" and "auction ending soon" for the
ones you have added to "your eBay" for monitoring.
Sometimes, some new parts from any retailer are incredibly expensives.
Being patient may result in finding a "as new" second hand or "NOS"
(New from Old Stock) item at a low fixed rate for which you will be the
only bidder. This is the most rewarding.
This is a
personnal example : I made a bid on an item sold throught eBay by an
individual. This item is a complete lighting / headlamp swith for Mk1
MGB. As I was the unique bidder, I bought it 5 GBP while it is sold
around 50 GBP or 70 Euros (knob NOT included) new from retailers !
