Our workshop hours are 8:00am to 5:00pm Monday to Friday.

With a large workshop of about 3,000 square feet and a comfortable air conditioned customer lounge we welcome customers visits to discuss their requirements and to offer helpful and friendly advice.

We are happy to book an appointment for your car at a time that is convenient to you.

We are quite unique in the way that we operate which means that we are normally able to fit your car in the same or next day, which is particularly useful if you have an problem with your vehicle that needs our urgent attention.

We offer a mail order and while you wait (by appointment) service for BeCM repairs, unlocking and testing
