Thinking about adding a sunroof to my 2005 Prius

welcome! no prolemo, a number of priuschatters have done it. i don't think it effects mpg's unless you have the tilt up model, and then, not much. check with your local mod shoppes. all the best!

 

When Toyota does it don't they add braces to the roof structure to maintain rollover protection? I doubt aftermarket installers do.

 

true, but how often do we roll over, really?

 

It only takes ONCE.

Start at a dealership.
That way you will have a price to compare.

Once you get the price, you might decide that trading cars would be cheaper in the long run.

 

I wouldn't. there's a very good chance you will end up with a butchered roof and a water leak. look at your cars roof from behind. you will see it isn't flat, but is lower in the center. who makes a sunroof with the correct contour for your car? if they chop a hole in your roof and then bend it to fit a universal sunroof, it will look like dooky at best. and if the POS jams in the open position, your car will stink like mildew forever.
I've repaired quite a few factory sunroofs in benzes-- they seem to break a lot. I'd never want a hole in my roof, just waiting fill my car with rain and make it stink.
