Welcome to the home of the MG Costello V8

This website attempts to unite the owners Costello MGB V8s of the early 1970s (and a few from the early 1990s) so that they may share experiences, admire each other's vehicles, and generally celebrate the car that convinced British Leyland to build their own V8 model. Their effort was not generally considered to be as good as Ken Costello's innovative 'original', thereby giving the Costello V8 cars a distinct cache, sought after evermore today by enthusiasts.


Ken Costello passed away in August 2015, and he is much missed. However, many of his cars live on. Listed here are all the roadsters, GTs, and restoration projects traced to date since January 2008. Those owners who have not so far provided photographs and details are encouraged to do so in order to make the site as exhaustive as possible. It is not currently known how many Costellos still remain, but so far, cars from as far afield as New Zealand, Australia and South Africa have been discovered, and there are plenty of enthusiastic owners in Northern Europe too. Currently, the owners of more than 65 Costellos have come on board, and now with a substantial press archive, makes mgcostello.com the nearest thing there is to a Costello Register, though it’s preferred not to be so formal.

About MGCostello.com

Having previously owned a V8-converted MGB GT, and various other 1800 MGBs Lawrence was keen to discover the merits of a Costello MG. With purchase secured he was sufficiently impressed and curious to task himself with finding all the other remaining Costello cars worldwide. More than 65 have now been unearthed to date and still the search goes on!


The result has become the first authoritative database on the marque; a compendium of useful and interesting images and information, and a long overdue tribute to Ken Costello himself; the man behind the ground-breaking cars.

From time to time, enthusiastic Costello owners gather together for a drive and to share stories and experiences. Fifteen such Gatherings have taken place in France, Belgium, the UK and Germany.

Take a look around and let us know your memories of these great cars.
