By me, the latter. Nothing against sex but I'd not defile my Prius in that manner. You do what you want, though.
I am in agreement - my ex had the gall to mention that to me and I said nobody is leaving any forensic evidence in, on or around my baby!
Yes; avoiding evidence of criminal activity in, on or around your Prius is a good idea, although you may want to use this time of renewal to make a full confession to the priuschat community.
Luckily and happily divorced with no significant other and purchased my Prius after I moved far and away - my Prius is clean as can be with no forensic evidence other than some sand on the floor mat from the beach. The infamous black light will not show anything. But, based on the amount of space inside and the original intent of the OP, maybe that is why the solar package has a MOON roof (I call it a sun roof myself)?! Good Gawd, that is a bad, bad visual... my eyes! My eyes!
I'm sorry, all I can think of is the forensic analysis of used cars I've seen on Top Gear. I may never be able to buy a used car again!
You never know what happens at the Toyota factory after hours. Working, all day, on those assembly lines must be frustrating and those workers have probably found some creative ways to relieve their frustration. Happy motoring.
1) Procol Harem for tunes 2) Backseat down. Beware butt prints on the glass. 3) Hood is good. Beware dust angels. 4) Front seats, across the divider. 5) Don't forget a dish towel. 6) People are everywhere nowadays. Location is everything. Good luck.
