Thank you for the good review, I hope the check engine light is staying off. The shop supplies charge is there on all invoices to cover the cost on supplies used during repair work. Smoke detection fluid for Evap system testing, hardware, penatrating oils, waste disposal, ect... The most important part of my job is to make sure you are 100 percent satisfied with us,so if you have any questions or concerns about the repairs or billing Let me know.
Thank you Charlie Burhoe
