I work in detailing cars, so basically my job entails that I wash and clean cars, inside and out.Besides minivans like the Toyota Sienna and Honda Odyssey, which are the WORST cars to clean because they're owned by the archetypical soccer mom, Toyota Priuses are a very close second.I don't think they're bad cars because we've bought literally over a hundred over the course of seven years from auctions and flipped them. They're not bad cars and are pretty reliable, but they're without a doubt some of the most boring cars to drive.Back to my original point - I don't know what the fuck it is, but in my experience, Prius drivers are some of the most filthy fucking people ever. 8/10 of the Toyota Priuses that I've cleaned were absolute nightmares to clean in the inside. And that's without any hyperbole. Everytime I get one assigned to me, it ruins my day because I know I'm going to spend the entire day, and in some cases two days, cleaning that filthy piece of shit.
