Guaranteed Workmanship on Car Repairs and Servicing


Miller Commercial Motors offer an unconditional 12 month or 12,000 mile warranty on all parts and labour whenever you choose our High Wycombe garage for car repairs and servicing. On modern vehicles, we perform car diagnostics as part of a full service to identify any potential sub-system issues and address them before they become a major problem.


Clients in High Wycombe can also book into our workshop for Class IV MOTs. We’re an approved VOSA facility with trained inspectors and the modern testing equipment. Most MOTs take around 45 minutes to complete. If you would like to wait while your vehicle is inspected, free tea and coffee can be provided.


While we are able to work on any vehicle make and model, we take great pride in being a Morgan servicing garage. Owners of the prestige vehicle marque use our High Wycombe garage for maintenance and repair work because of our in-depth knowledge of this timeless brand. Free estimates are available on all garage services.


Don’t forget, we welcome customers from throughout the Buckinghamshire region. Our company is committed to becoming the number one choice in the area for all your car maintenance and repair needs. This is why motorists from areas such as Flackwell Heath and Loudwater, are already coming to us for car servicing, MOT testing and similar services.
