I contacted a company that makes window vents to see what it would take for them to make window vents for the iM. They currently make them for a ton of vehicles including the new Corolla hatch (pic below). I will just copy the email straight from them and hopefully we can make this happen. I understand that this is a love/hate product. Some climates their great for and some are not...
“Thank you for reaching out to us. We would be happy to offer window vents for that vehicle. We have 2 requirements for a new line of window vents.
1) A minimum of 7 or more individuals willing to place a preorder at 15% off retail. Retail pricing is $160 without mesh and $190 with mesh plus shipping. The preorders would be 15% off that pricing.
2) An individual with the same model vehicle local to Bohemia, NY that is able to drop off the vehicle for a couple hours for us to design and test fit the window vents.”
