Whilst we have a fantastic reputation for German cars, we happily assist all makes and models.

We are located a few minutes drive from the M25 and around 3/4 of a mile from Little Chalfont Underground and Chiltern mainline Station.  This makes us easily accessible from London, Buckinghamshire, Hertfordshire, Bedfordshire, The City and Canary Wharf.

BMW Service and Repair We have a fully equipped workshop with the necessary diagnostic tooling for BMW and other German Car models. Our experience ranges from the reassembly of the only 3 BMW RHD 503 cabriolets to the fitting of superchargers and E39 M5 engine rebuilds , as well as more general service and overhaul. Whatever BMW you drive, we will be able to provide the full service to meet your needs. Loan Cars can be made available if requested in advance.
