The UK and Europe's largest vehicle auction company is moving its business centres from Newport in Wales and Tewkesbury in Gloucestershire to Bridgwater off the M5.
The centre off Junction 23 is a 20 acre site with two auction halls and sheltered viewing for 600 cars.
It is said to be located in an active catchment area in the busy M5 corridor, which could help to bring in more business.
Locating the site nearer to the south west of England will give BCA more opportunities to reach local and regional customers to help expand on the increased market activity generated, the firm indicated.
BCA's UK managing director, Andrew Hulme, said: "We have taken the decision to focus our business objectives in the south west onto our existing supercentre in Bridgwater, where we can offer all our customers a first class service in one of the best appointed remarketing facilities anywhere in the UK."
Many BCA staff have relocated and the Newport and Tewkesbury operations have been mothballed.
