While we detest the word "policy", and prefer to address specific situations individually, any services or repairs performed with customer-provided parts forego our warranty. Should the parts you provided be wrong or faulty, you will be charged for the time your vehicle ties up our facility until you can re-source, pick-up and deliver the correct parts. Additionally, we have an administration charge for handling outsourced parts. Essentially, our services and repairs must be successful; this success is not possible without complete accountability.
