Judging by the way the wifey screams when I leave the blinds open and sunlight hits her new couch I'd say you got something to worry about.

I like the Porsche indoor car cover, super easy to take on/off and friends are way more impressed with your Porsche when you make them watch while you take the cover off, so win-win!

do you guys have a source for this?

I drove for 6 hrs one direction in direct summer sunlight in a modern car with windows up a couple years ago and got a mild sunburn

Yes, but sitting outside for a few days is different than sitting in sunlight for 365 days a year for who-knows how many years. My main concern was actually due to where the sun comes in, if certain parts would start showing some discoloration quicker, especially due to the ppf since yellowing is somewhat inevitable over time.

Quick anecdote: In our last house I bought a brand new leather chair and left it in a corner with the shades open 7-days a week due to some plants we had, and only 12 months later that brown couch is two-tone from the half that got direct sun. The glass windows didn't seem to help much...

I get all the sarcastic responses (and was expecting them ), but do appreciate the serious ones.

I was not joking about duct tape and cardboard. Then again, I am generally nocturnal and dislike natural light.

It is true, seen the actual data. When I was a resident more than 10 years ago, one of the students actually went and measured the UVA and UVB pass through values for many cars. Long story short, cars after 1998, blocked UVA and UVB through side windows. All blocked UVB through windshield. Some dars let through some UVA from the windshield, but still blocked UVB.

UVB is the bad apple and is what causes mutations, UVA is responsible for tanning / darkening. But it is still bad.

Just for the detail oriented.

UVA and UVB are just arbitrary names. Here is what they mean.

uva: 320-400nm wavelength. Can penetrate deeper (up to fat under skin). Main wavelength range that causes skin tanning and responsible for skin aging

uvb: 290-320nm wavelength. Not so much penetration (doesnĺt reach the fat under the skin). Main cause of skin cancers.

PS: for perspective, visible light ranges from 380-400nm (violet) to about 700-740nm (red).

And dont mean to insult anyone, lots of you science geeks already know this.

Indirect light is not going to damage anything. Also, even a little bit of direct light will do more good than bad. Modern cars have very effective UV-protectant compounds in the clear coat, plastic and leather surfaces, so a little bit of light will not damage anything, even if that was direct. Do not get obsessed with covering windows or anything.

This can't be real... right? Worried about some diffused sunlight hitting the car.

If that's your game, I respect it. Tape the windows up if you makes you sleep better. ?

Default Hire a Window Tinter

Really easy solution: hire a window tint installer to apply flat-glass window tint to the windows. It will let in as much light as you would like, while significantly reducing the UVA/UVB rays and heat that come from the sun.

The same characteristics are why you should tint the windows on your car; you're protecting yourself and the car's interior while you are driving.
