My 2 cents - I have two kids and the Bolt is plenty big for the 4 of us. We've taken week-long vacation trips in it. The most ambitious trip included time at the beach, time in the mountains, and a few nights camping in between (so we had our tent, air mattress, sleeping bags, chairs, etc. all packed along with the 4 of us. IMO the VAST majority of people who say the Bolt is too small if you have kids simply don't know how to pack properly. The only exceptions are things that are legitimately large. For example, my son plays the double bass and we cannot fit it and the 4 of us in the car. But we rarely travel with it - only to local concerts, in which case we take two cars.
Also, I too miss the lower seating position. The car handles better, plus you just feel more connected with the road. It's a much better experience all around. But those don't sell any more so most of them are gone. I REALLY miss the import sports coupes of the 90s. I wish someone would make a sports coupe EV. It would be a great commuter / around town car. The Bolt is already big enough for my family of 4 and our stuff. And my wife and I need two cars anyway (two commutes in opposite directions).
