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.
A number of years ago I got in an accident with my Q7 and the body shop said it was cheaper to buy brand new headlamps than used ones. They’re the self-leveling xenon with the LED surround. They were around $1700 at the time. $4000 doesn’t surprise me on a newer fancier model. Still outrageous though.
