It's the complexity of vehicles and inspection requirements that is the downfall.
Three instances have hit me with failed inspections on things that didn't matter to me.
1) 2009 VW - Turn signal blinker on the mirror AS WELL as under the taillight. The blinker under the mirror went out, car failed inspection. I did not need or request that blasted blinker, I WOULD NOT have paid for it if it was an option. Several hundred $$ to replace.
2) 2019 Ford Escape - Parking sensor on right side went out, failed inspection, estimated cost to replace $600, requires pulling bumper. Again, I didn't need it.
3) 2024 Ford F250 diesel SWB CC - Backup camera. Recalled due to moisture in lens. The whole DA$$ truck was fine. EXCEPT the blasted camera!
Bells and whistles might be nice but if they fail I can do without them.
