Types of Service & Repair For Your Bentley

Flying Spur repairs at our Chicago area Bentley repair shop.
Your personal driving style and type of daily use can affect the maintenance and repair requirements of your car. This is condition based maintenance. At every visit, we’ll inspect your car to establish condition, safety and wear. The inspection results and diagnostic recommendations specific to your Bentley help you to effectively plan for future maintenance costs.
Servicing and maintaining a Bentley often requires a different approach to many other vehicles. In many cases, Bentleys’ are stored over the winter period in the Chicago area. This produces a shortened time over which mileage occurs and with a long winter, can result in the vehicle sitting still for three to four months.
Bentley recommends 10,000 mile or 1 year time based service intervals. Some service items, such as brake fluid or coolant, degragde through time as well as mileage, so an annual inspection and service, regardless of mileage is important to address these items.
Below is a list of services and repairs we provide to our Bentley customers. If you do not see the service you require or have questions regarding a diagnosis of a vehicle problem, reach out to us at (708) 687-5258 or use the enquiry form below.
