This is not a change but an add on. Both of our cars have "rain guards" on the windows. This are a great product and I'm surprised more people don't use them. The advantage is that you can leave your windows cracked an inch or two and if it rains no water gets inside. Now, the reason to leave the window cracked is because of heat. We live in south Texas and it gets sweltering sometimes... it's 104 out side right now. Leaving a car in the sun with the windows rolled up tight can cause the temp inside to get to 150 or even higher. This is terrible for the interior vinyl and especially leather, causing it to become brittle and crack. So, even when there is no chance of rain they are still useful. As a bonus they tend to hide the fact that your window are cracked so you don't attract thieves. I hope someone will make these for the Elio, I'll be the first to buy a pair.
