I'm very tempted by the new Duster (I saw one in Renault Cardiff yesterday). I don't really do enough miles to warrant a diesel, but I would want the highest trim and diesel is the only engine available. Mostly it would do short journeys in town (a few miles, once or twice a day), but with a 10 mile run at 50+mph 3 or 4 times a week. Would the frequent short journeys likely cause DPF issues (or any other issues), or would the longer runs be enough to keep everything healthy? I'd be looking to keep it for 3-5 years (probably getting the 2 year extension on the warranty).
