Moving them out of the house and into your trunk is probably dependent on where you live... I couldn't do that here as it's 3-degrees F and the plants would all freeze! So, I'm not going to comment on that (but I agree, you need to get the plants out somewhere else if you can)... If you're also going to be trying to mask the smell, sauteeing onions and garlic is probably the best (pretend you're in the process of making a stew!)... those two scents will mask just about anything...
