Our business is based on a love of Alfa Romeo's and our business is now in large premises in Caerphilly, South Wales, and we continue to develop the craft of classic car restoration whilst specialising in selling Alfa Romeo parts.

​

Everyone at AlfaStop is passionate about the Alfa Romeo restoration process. All our team own and drive classic cars and this passion drives everything we do.

​

As passionate classic car owners ourselves, we understand that to their owners, these cars are more than just transport, but are often the realisation of a lifetime's dream and years of saving – so you can feel comfortable that the if we are not happy to fit parts we sell on our won cars, they won;t be sold by Alfastop.

​

We offer an extensive range of quality components including brake parts for Giulia 105 series cars fitted with the ATE system, clutches, exhausts in both normal steel and stainless steel, new range of suspension and transmission parts for Giuliettas & 101 series Giulias, and books and manuals.
