Advice for the smaller car life?

I've been living in my car for about 2 months now, and at this point I feel like I'm reaching the limit of how comfortable I can get without buying something bigger! (which the funds won't allow) .

For context I'm 6'1 155lbs and my car is a 2005 Nissan Tiida hatchback (I know, the worst car to sleep in at my height! lol)

I'm currently crashing in in the passenger seat reclined all the way back which gets my legs somewhat stretched - but just checking if anyone's done anything to their smaller cars that have improved comfort/organization? Any ideas or tips would be awesome.

Best of luck to everyone car-camping!
