I have had the Audi Q5 and wouldn't have another.
Its was the plug in hybrid, in the 18 months i had it from new, it had, a repair to the charging point, then it was replaced, rear view mirror fell off in the heatwave, so it had to have a complete new windscreen, the rear drivers window stopped going up. it has a creak/metal fatigue noise every time i pulled away, the passenger side mirror had a creak every time i opened/locked it, body trim pieces that kept moving and hitting the door pillar and other niggles that im not going to type. in the end, it got a running joke of what noise would appear everytime i got in to drive it
so it has now gone back to Audi and hopefully it serves the next owner a bit better than me. It cost £55K and i was deeply disappointed with the quality. i still do like the look of the audi's but have been put off by this. I also had the Touareg a while back, which i couldnt fault, that did drive nice. but all the sensors/electronics always worried me that it was going to cost a fortune when it did eventually go wrong. (same with all new cars)
I looked at a disco 5 before the 150 too, that did drive nice but got put off about the cranskshaft deciding to part ways when they like. Also the Fugly back end.
cant comment on the Merc GLC, that was the other option when i was looking at the Q5 but Covid kept getting in the way with testdrives etc.
I hope what ever you decide on serves you as well as the 120 did.
