Oh, I looked around a ton before I bought my 1996 Tacoma. I test drove a lot of new and used stuff. I ended up going with a new, basic Tacoma. In that basic set up, they had 2 on the lot (huge lot, we walked the inventory lot). I went with green over purple, but I was ready to pull the trigger on purple though.
I should note that I financed that through Toyota back then too. If the sales guy didn't like me, the finance guy hated me. I knew the numbers, computed the payments before he could, and called him on stuff he was trying to add without asking.
In the last 3 years, I've bought 2 vehicles. My wife's 05 Xterra was totaled in late 2015. Shopped around for a while, test drove several vehicles, and ended up with a 2016 Subaru Forester. I was looking to replace my 07 Honda Accord before I had to do the timing belt again. I was in no hurry, and I started that process early. I ended up finding a 2015 Tacoma with low miles with a 6-speed manual for a reasonable price. I pulled the trigger on it, and sold the Honda on my own.
In terms of your question about which model I would buy among those 3 choices, I'd have to test drive them. I'm doubting that I would deem any of them practical given that I have to fit a car seat for a 20-month old while still leaving room for an adult to sit in the front seat right now.
