Car:
Get a Toyota Corolla, atleast Gli 2012+ model. It will be comfortable and parts will be easily available. You'll drive it alot, but you won't have to worry that much about resale. If you want something with decent fuel economy than a vitz or something like an Aqua would do.
What i reccomend for setup:
Use your phone on a phone holder to record yourself speaking.
Get a decent dashcam , such as a gopro, or you can use another phone (used Samsung S5 or better, or an iphone 5s or better) on a phone holder to record the road
Video shouldn't be longer than 10 mins in my opinion ( you can make parts)
Make a series such as :
Trip to Naran PART 1 (Peshawar to Abottabad)
You would record a brief intro in begining, give a few clips of the road, and in the end, take a break and use a phone with a good front camera to summarize how that part went.
When the series ends, you make a vid with a detailed review of the trip and your reccomendations.
