Hi we chose the T4 RDesign pro because we always liked the xc40 but last summer the AP was £3500 which was a bit rich for me so when last December the the AP was just over half that so went for it, If you don’t do many miles then it doesn’t matter so much.we tried a diesel and it felt a little more low down grunt but when automatic it really doesn’t matter so much and the petrol T4 was so much smoother than the diesel also as the AP was about £1200 more you would never cover that cost,in all fairness I would have chosen the inscription interior over the R Design but the RDesign outside looks much nicer,to me anyway
