@Eiswald @bronze @JedKron1248 @justnormalkorean @Hoss >tbh I foresee a whole 'black market' for jail broken cars or a regression away from this tech

Just look at the used diesel truck market. Diesel trucks from before 2006 and especially made in 05-06 hold their value extremely well. Sure they have EGRs and some other emission components, but they are nowhere near as problematic as the DPF/DEF systems, and due to their lower production numbers compared to say a car from that year, they hold their value extremely well compared to a gas truck of the same year.

Or the "Glider Kit" loophole with trucks, or why a lot of diesel car companies had emission scandals at the same time (the DPFs on modern diesel cars need highway driving), or why big block gasoline engines made a comeback. The Ford 7.3 is for school busses as a "diesel replacement" and the like, not Mustangs.

If it gets bad enough, you'll be seeing forum posts about how a guy bought back and fixed his totaled car with nearly 400k miles just to keep it on the road because there's no replacement. Some guy with a NMS TDI Passat on a forum already did this.
