How to film a movie scene in a car?

I have just written a script that requires a scene shot in a car ride. I have three cameras, an iphone, a camcorder, and an actual film camera. I'm new to film making and I really don't want this car scene to look like something out of a reality show. If you have any tips or advice as to how to shoot this scene I'll appreciate it very much.

What are the main & major difference's between an iPhone 6 & the 6s?

As I'm going to buy my first iPhone next month so,6s & the 6 looks too much similar from the exterior don't know about the interior though.

Buying 6 instead of 6s would save a bit of money to me.
But still would love to seek guidance from you guy's that what are the major difference's.

Spam Text message from my own number?

I have iphone still on ios 6 and received a text message which says its from myself, by my first and last name which i have in my contacts on the phone. The message had a link to a site, i never clicked the link or anything but since my phone is jailbroken and has this tweak that automatically replies to sms messages when the phone is in Do Not Disturb mode, i think the tweak is called autoresponder, and since my phone was in Do Not Disturb mode when i received that text it replied to it. It replied over imessage and then received the exact same message back.
eg;
Me: hi, sorry i'm not available atm.
Sender: hi, sorry i'm not available atm.

so now it seems like i'm just talking to myself over imessage.
i don't know, anyway just wondering if they could see that and now know that the number is real and will they likely keep sending spam.
