Part 1
a. Original Parts
What are they?
These are original Vauxhall parts, supplied in Vauxhall-labelled packaging. Vauxhall do not actually make most of their spare parts themselves, instead they order them from other manufacturers who specialise in the specific area. For example, Vauxhall spark plugs carry the Vauxhall label both on the part itself and on the packaging, but they are in fact made by Bosch for Vauxhall.
Where can they be bought?
From Vauxhall Dealers, from eBay (though beware of fake items), or from firms specialising in Vauxhall spare parts.
What do we think about them?
Vauxhall parts are usually of very good quality and are reasonably priced, and as such they represent very good value. In the vast majority of cases we would recommend the original Vauxhall part because you can rarely better it in either quality or price. In addition, you are more likely to get the right parts for your car (although Vauxhall dealers have been known to make mistakes…).
b. OE/OEM Parts
What are they?
OE/OEM stands for Original Equipment Manufacturer. As mentioned above, most Vauxhall-branded parts are actually made by other automotive manufacturers. These companies also make the same parts for marketing under their own brand name and through their own distribution channels. For example, Vauxhall’s Cambelt Kit is made by Gates, so you can buy the same kit either branded as Vauxhall from a Vauxhall Dealer, or branded as Gates from a motor factor outlet.
Where can they be bought?
Motor factor outlets, eBay, online shops.
What do we think about them?
In principal there is nothing wrong in buying the same parts directly from its manufacturer. The theory is that is should work out cheaper, and in the case of the Cambelt Kit it does. However this is not always the case – for example Bosch-branded spark plugs are actually more expensive than the same Vauxhall-branded ones… So OE is OK but compare prices first and don’t assume that it is always cheaper than the Vauxhall-branded item.
