A Cybertruck would be cool but not really practical for me. I also think she'd spot it if I tried to justify buying one on the back of carrying her bikeFor truly loading capacities I would guess cybertruck or the Rivian one would be ideal. That's my plan at least for when the kids grow up and i would have to carry mountain bikes etc
I've been well impressed with the 3 for load carrying and I can get an XL mountain bike and camping gear for a week in there without too much hassle. But the extra space would be nice. One "regret" I do have is not going with a towbar for a bike carrier (two bikes and take the missus) but that wasn't an option on the M3P. There's still a roofrack option to investigate for that.
So I'm not desperate for a Y just yet although it will become more tempting down the track in 18 months or so.
