Unless you want your kids to hate you…
It’s a no brainer.
6 kids - you need a minivan or a bus.
Nah. With 6 kids you need a sports car. Because you would want to get away quickly on your own from that madhouse.
I also say Van.
If you want the 2020, you can do better than 4.99%. Penfed offers 2.99% on 72 month loans. That is probably a 60 dollar difference in payments. Anyone can join Penfed, I have ten dollars in a free account with them since they offer a Volvo rebate in the DC area.
Also, I get wanting the vacuum, I know how messy kids can be. I bought a little car vac for my car. Then decided screw it and bought a couple model year old Dyson cordless vac and some car cleaning attachments. I keep it in the garage. I now prefer it to any corded car vac.
On the vacuum point, I can say that the built in is ideal for road trips when you get to your destination and have all sorts of detritus to suck up. It is nice to not have to drive around in a scuzzy car the rest of the week at your destination. You can of course throw a cordless in there to bring, but it is just one more thing to pack and remember. But, since no one has built in vacs available right now in '21/'22s due to the supplier issues, I guess it doesn’t really matter!
