Picked up a 2018 SQ5 recently. Its the 3.0 tfsi (no diesel content here!). Moved over from a BMW 440i grancoupe (with the MPPSK) which I kept for 2 years.
Not driven it much tbh, just between home and work so getting used to the car. A photo when I collected the car:
It won't go through puddles deeper than the height of the exhausts. Electronics inside can cause a major poblem when wet apparently. I think the SQ5 is quite nice and considered one as a gap car but it rains and snows quite a lot in the High Peak during winter so discounted it.
