A water pump is $38, $89 or $214 depending on three letters nobody explains at the counter. PartScout prices the exact part number live, decodes what each tier actually means, and hands you the questions that keep a $600 job from becoming a comeback.
Free decode
The search above prices parts on live marketplaces. The box below decodes your paper: the estimate's part line, a listing you're eyeing, or 'which brake pads' as a tier question. Labor rates and whole-estimate checks live at Car Repair Check — we link there instead of duplicating it.
Live listings — published marketplace APIs
Why this exists
OEM means the automaker's box. OE-supplier means the same factory's box without the logo — often the identical part. Aftermarket runs from excellent to economy. Shops mark parts up as standard practice; the number on your estimate is a starting point, and the part number makes everything checkable.
How it works
Part number or description — live marketplace listings side by side with links out.
OEM vs OE-supplier vs aftermarket for YOUR job, framed as what to verify, not brand war.
On a paid plan: the buy sheet — cross-reference numbers to confirm, supply-your-own-part questions, and the warranty-of-repair trade-offs in writing.
