Hi, we love our Qubo, it is nimble with good headroom and space. Look for the 95hp option. I used to commute 15 miles each way on single carriageway roads with a weekly run for 30 mins on dual at least, never had DPF problem. It regenerates every 350 miles or so.
Now at 99000 I have started a much longer commute of 37 miles down the A11 and am surprised how easy it has been in the Qubo if you coast with the traffic 67/70, getting 50mpg or more. It can keep up in the fast lane but gets a little noisy.
The car always handles well, never does anything lary on rutted, potholed or awash roads, a much underrated car. Similar great view of the road with good upright seat, looking through the middle of the screen. Find reclined saloon style seats very uncomfortable now with a pitiful low view over the dash to the road.
