Hi Joe,
we have an '07 Hyundai Tuscon which is the previous one to the iX35 and cannot fault it. Currently have about 230k kms on it and other than normal servicing the only thing that broke on it was the EGR valve which was about €350 fitted from the main dealer in CW. Ours is the LTD Edition 4WD version 2.0TD 140bhp leather, with enough power and traction, bigger tyres at 235/55/17... and still returns around 42Mpg average. The one with the narrower tyre and 2WD is easier on juice.
The inlaws have an '09 Qashqai 2WD 1.5DCI... it is a little bigger... a good bit easier on the juice as probably avg about 50-55Mpg and even better on long runs. Residuals on Qashqais are good, especially the ones with the smaller engine as easy to run and big space to haul family around. However, the engines are soft in them... and niggly bits go wrong with them like trim, switches, etc... they're just not as well made and hardy as the Hyundai. Also of course the Hyundai has the 7 year warranty thing, which not only is peace of mind for you, but shows they are willing to stand over their vehicles which our Tuscon is testament too.
Hope that helps.
