View Full Pricing Guide →⚠️ Beware Overlap Labor
Dishonest shops often double-dip labor when billing multiple Op Codes. For example, if parts must be removed to access Door Lock Replacement, they shouldn't bill full Book Time for both codes.
If one door handle breaks, some might upsell others (“they’re the same age, could break too”) - usually not necessary; using only dealership parts (which could be pricey) when aftermarket is available; not clarifying if the handle comes painted or needs paint (some come raw black).
