We all know OEMs can have huge markups/high MSRP’s on parts, but there are some things that are truly outrageous out there. For example:
Ram windshield washer nozzles: $100 PER NOZZLE! (available on amazon for a pair for about $15)
A rear park sensor on a 19 caravan listed for around $400, non-colour matched, while the same part on a 16 mercedez was $180.
Don’t know if this counts, but the MT-82 in the Mustangs is knows for having a pos throw out bearing. It’s a $80 part but you need to drop the transmission and remove the clutch system to replace it. $80 part but nearly $800 to replace.
