Point taken. Then your solution would involve midgets/andor prostitutes.
David and I had a retarded conversation, and he said he can fit 5 people in his 350z-- I countered with 7 people in a 3-series sedan, or 9 dead prostitutes, or 10+ midgets.
So, depending on your local availability, I’d suggest a 20% tint or higher, and no-one will be the wiser! 
J/k, J/k. You can’t really see whether or not there are people inside with a good tint!:R
