Toyota, Honda, and Kia all have major manufacturing plants in the U.S. Any car you buy will have been "Made in America."
I recommend you look at a used minivan if your budget is $20K. That's about what we got our Honda Odyssey for, used but only 3 years old, plus with our trade-in, we paid less than that.
I love it. We have two kids in car seats (a 3-year-old and a 16-month-old) and are hoping to have a third in the next two years. We will easily be able to fit 3 car seats in the van.
Bonuses to minivans: Sliding doors. If you get the right model, you can open and shut the doors with the keyfob, meaning you can carry a baby, a couple of bags, hold your child's hand, and still open the doors! Other pluses: usually better gas millage than SUVs, 3-rows of seats AND trunk space (you don't have to trade one for the other like you do with crossovers) and most car-seats fit in them. We will have plenty of room for a family of 5 plus our dogs plus luggage for road trips.
My husband has a sedan. It is very nice, too, plenty of room for the four of us plus luggage or a dog, but not both, and unfortunately, no room for any forthcoming children. So this will make a difference. We looked into crossovers when we were car-hunting originally, but ran into the same problem. If we got one with three rows of seats, there was not really room for luggage and a dog, and if we didn't, there wasn't any room for a third child. That is how we ended up with our minivan.
We chose a Honda because they last forever.
Good luck make a decision!
P.S. I'm from Bloomington! What a great town!
