Thank you everyone, for your replies.
I ended up trying it out on a camping trip last week and I must say.....I really enjoyed sleeping in my Versa!
It did take some fanagling though. I pushed the front seat forward and then the seat back all the way down (taking the headrest off first). The seat then meets the backseat so it is practically flat. I am 5' 5" and can sleep full out. However, there is kind of a dip in the actual seats so I had to put stuff there to straighten it out. I used a airplane neck pillow on the rear seat and a folded yoga mat and flat pillow on the drivers seat. I also had a foam thing that I put over it all, with a cushy sleeping bag on top.
It was more comfortable than the tent because the tent folded up at 3am due to high winds! lol! Thankfully, I had the car set up done as a backup already.
The goal was trying to see if I could get it to work well enough, without having to buy anything new. It worked! So now I know that I have no excuses, I can get out of town anytime I want, and I don't have to wait to have the perfect equipment or rig. I'm living in LA right now and its driving me bonkers! I need to get out every now and then to regain some sanity.
If I was planning on full-time living in my car, I would do things differently and probably get a Prius. But for now this worked.
I do want to move towards the full-time nomad life eventually, so I am in the visualizing and fantasizing part of the dream now. Every day I change my mind as to what kind of rig I would like to get.
