Jeez---another "can I sleep in it?" post. If you search you will see lots of posts about this.
The short answer: NO.
Keep your 4runner, and breath that car air all nite. The only time I would ever sleep in my car is if I was afraid to pitch a little tent. Sleeping in cars is disgusting. Making love in cars is interesting.
Can you make love in an FJ?
I think so......
PS I do like your side by side pics
