In general he should be ok. It REALLY depends on the bunny though. Some don’t handle car rides well at all.
The general advice is also to leave them alone in their base for a few days to a week (I’ve even read two weeks)!
With my fluffykins he wasn’t phased at all with the car ride home (and it was 1.5 hours for me too) and as soon as we got home he was SO inquisitive. We set up a little barrier with our legs around the cage haha and left the door open and he just shot out, straight up onto each of our legs.
He is a very snuggly bunny. We played “with him” like that on the floor for a week or so before we began to interact more. So for that first week he just climbed all over us. It would have been punishment / torture to have him caged up and us ignoring him for a day, let alone a week… So my point is, it’s general advice.
It most likely will apply to the majority but please also apply common sense and read your own buns signals as they come. If you see he’s confident and very very brave, and taking these new changes in his stride, you can act accordingly.
