I'm still keeping my eye on them and they're just creeping below the £30K mark, would really like to have a test drive of one. Like you say it ticks a lot of boxes for me too, it's a decent sized estate with a flat boot area (annoyingly an optional extra on the Arteon/Octavia/Superb), it has a good spec including blind spot monitoring (a must for me)and while less important I think it's a good looking understated car.
I was pleased to get a Toyota Prius self charging hybrid hire car recently which is similar to the Toyota Corolla estate I've been considering to replace my current car although wasn't keen on it which is making me more interested in trying the ID7. I'm hoping my current car will last a while longer and I think by the time it needs replaced there will be more pushes to go electric.
