Car sex??

so my boyfriend and i want to lose our virginities to each other ☺️ problem is, we're both in high school and our options are limited. both of our homes are never empty and we can never find the time to be alone. is it okay to do it for the first time in his car? i know this sounds like a stupid question lol but i just want to know if its going to be really hard or not. he just has a little mazda car, i don't think the seats go down so it would either be in the backseat or passenger. idk. tips pls?? 😅
