Nah, most newer cars have one of them usually. So far I've avoided DPF's with MK4 Golfs and a Vectra CDTi....however both have had (and broken) a DMF.
The way to avoid it is buy older or buy petrol unfortunately!
In the case of the 307 though, yeah the 2.0 HDi 90 is the same as the one in 306s, so none of the newer things. Mate at college bought a 1.6 HDi XSi and had no end of engine problems with it, DPF, injectors, electrics, wasn't even high milage. The seats were nice though.
