Where overcharges hide
- Parts markup. The most common one. If the part on your quote is far above the retail range above, ask the shop to price-match or let you supply it.
- Inflated labor hours. Compare the hours billed to the typical range; padded hours are a quiet way to lift the total.
- Bundled upsells. Fluid flushes, filters, and “preventive” services added to an unrelated visit with no stated reason.
- Lumped line items. If part and labor are one price, ask for them itemized so each half can be checked.
