Don't get me wrong, the above was annoying. But they were forced to pay for it and I came out ahead. There's no doubt in my mind that my 2012 model still polluted less than my former 1998 model. There were many times before the scandal broke that I considered removal of the DPF component to further improve efficiency. This would not have affected the NOX output, but would have reduced weight, fuel consumption, and cosmetic appeal. I wasn't keen on having the car blow raw diesel into the exhaust to regenerate the filter every few hundred miles. Would have averaged 50mpg instead of mid-40's...

I put over 100k mi on the car and will have received approx $19k for it after the goodwill + buyback. Total cost of ownership for 4 years of about $6k excluding fuel which cost about half as much as a gasser (savings was anywhere between $3-6k). So yeah, pretty happy all things considered.
