Most urban based buyers would be interested in the crdi options.....................why ?, short distances clog your DPF which ia a pain the *ss, you're constantly clearing it regenerating, own experience . He's copying economy as provided by the manufacturer, real life is almost always worse, why not give us actual figures ?
my i20 1.2 2011 had it 4 years been very reliable , plus last 4 MOT since ive owned it a clean pass each time not even an advisory, cheap to run and wear part they been cheap too and currently look at the face lift or the next gen been happy with mine was only going to be temp car up to 12 months but still looking 4 years later for the right one , only thing id do on next one is higher spec as want cruise control and few other extras, the only thing id change if new gen is basically the same better suspension still soft but more control at the higher speed bumpy corners as they can really unsettle the car and as long term car may get a stage 1 ecu for tad more torque but 118nm is not bad anyway for 1.2 non turbo but a little extra always good
