DPFs and the future of diesel autos: Discuss

So, the French chick's 1.9 diesel Fiat is nearing the end of life-- motor is still going strong but lots of other things are wearing out after 20 years of good service. Thus, we're shopping for a replacement. Used. Was looking at newer diesels but then ran across all the horror stories DPF (diesel particulate filter-- mandatory in EU diesel powered cars since 2009) failures (perhaps that should read DPF-induced failures since much more than the DPF is at risk). The repair bills are staggering (at least to this country boy). It has me considering buying older just to avoid a DPF altogether. Or, perhaps exploring the benzine/GPL or benzine/metano offerings in the newer cars (that is gas/LPG and gas/CNG translated into N. American). I suppose that statistically, the DPF problems are still rare (they sell millions of diesels here after all) but the reading is chilling. Anybody here have a calmer, wiser, analysis?
