Some of us "armchair automotive engineers" own and operate DPF equipped diesels so we have lived with their requirements. But you can also refer to the supplemental manual GM includes with diesel equipped vehicles which explains the DPF and its behavior. If used primarily in stop/go short commutes you are going to have to plan on going for some extended drives when it tells you to do so and if you don't the filter loading will quickly reach the point where the next step is limp mode and a visit to the dealer where a forced regen will be required.
It is something a potential new owner needs to be aware of to see whether this operation fits with his planned usage. The owner can't choose when to periodically drive it for the extended time because that is determined by soot loading.
For most people the DPF won't be a major issue but if the OP isn't planning upon significant operation outside of his short commute he will have to plan on letting the engine controller decide his driving plans at times.
