Hyundai I40 tourer as a tow car

Hi does anyone have a hyundai i40 tourer that they tow with, I'm thinking about getting the 1.7crdi 136 bhp for my outfit.  this easily meets the 85%ratio for my caravan,  but does it tow well! is the rear suspension soft as was alluded to in the recent  CC tow car review it said the rear end dropped a couple of inches. Any feedback would be appreciated as I don't want to make a poor choice

Thanks
