Family of five with 15, 10 and 4 year old. The 3 replaces my S and it works well despite my wife’s trepidation. The key is your lifestyle. I rarely have more than two kids in the car at one time. The 3 is a commuter and then take [insert] kid to and from practice, class, etc. We have a minivan for hauling multiple kids.
My oldest prefers the S but I’m the one with the smile on my face every time I drive the 3.
I will (almost) never have more than 2 kids in the backseat, so just need to optimize for the family of 4. Based on all of the responses so far, it looks like M3P is the way to go for my driving enjoyment, comfort and saving some decent $$$. I appreciate all of the insights, I had surgery this past week and I am sequestered for the weekend, so doing as much research as I can with my free time before setting up the overnight test drive.
