Circumstances have me re-evaluating my Model 3 reservation. For those with young kids, or those expecting -- how do you anticipate the size of the M3 will work for you? Also, for those with the model S as well...how does the sunroof work out for kids with rear facing carseats? is the tinting enough where the sun isn't a b!tch? This wouldn't be the primary family car, but will need to accomodate kids so for the next 5-8 years so i want to make sure it's a good fit. I'm confident in the safety of the car, but could use some wisdom on the joys and struggles of having kids and driving a sedan. Thanks!
