At 40k check the Haldex has new fluid, and the filter cleaned (sometimes they don’t touch clogged up filters). Ensure both done if buying
Check the tyres, if previous owner has swapped them (and 4x4 versions require them swapped around as per handbook), could all be original summer tyres (check date codes, a 4 digit number, 2 digits week 1-52, second 2 year). If it has mixed tyre types the Haldex will have had harder time. The Karoq really needs all season (or winter) tyres in cold weather, if summers used during cold there is likely to be lots of surface cracking
Wheels : UK spec comes with large wheels, great in a showroom, useless for good ride on poor tarmac, and prone to damage on potholes. The tyres for these are often weird sizes which means limited choice and expensive tyres. Consider changing to smaller wheels (link has full range)

Then check everything works, put it in neutral with someone standing behind watching the exhaust, and blip throttle. If engine accelerates slowly or smoke comes out of exhaust then you might have clogged exhaust filters (virtually impossible to fully clean without removing from car, as a DFP regen won’t fully clear out existing ash)
