To no one's surprise, I returned the i5. The biggest issue was the car was clearly owned by a smoker, and despite it being run through their "fumigation" the smell returned. Add in some strange loose trim rolling around behind the air vent and the rear seats squeaking due to not being properly attached, I had them take it back. We also both agreed that the BMW seats just aren't working for us, the lower part of the lumbar which cannot be deflated causes us both aches.
So we used this as an opportunity to scale back the budget (we weren't that happy with the amount the iX and i5 cost) and get something that is more familiar.
We knew we wanted Audi, as our B9 A4 Avant was very comfortable. We tried a lot of different options from them:
Q8 e-tron - not convinced by this as an EV. Pushed the budget up £6-7k for what we would want anyway.
Q4 e-tron - my wife liked it, but the integrated headrest into the backrest caused her immediate discomfort.
We took a model 3 on an extended test drive as they are very reasonable on lease, but ultimately the seats didn't do it for us and the lack of CarPlay would annoy both of us.
So while not full EV, we decided to take a step back and go for a hybrid for the next 4-5 years. Picked up an Audi Q5 55 TFSIe Competition, with that lovely b9.5 interior. It's in fantastic condition, 22,000 miles. For our driving, 90% will be done on the battery.
