I have a 06 525i jet black with beige interior. Anybody have recomendations on a window tint that is not too dark but will reduce the heat factor while driving and parked. I want to maintain the contrast look of jet black against the beige interior. I have not idea what the percentages mean on tint that are available. I will have it professionaly installed.

 

The percentages mean the amount of light at is let through, for something not to dark I would go with 35%. I have 20% on mine and it looks pretty dark.

 

If you are interested in keeping light out then go for a dark tint like a charcoal colour.

If it's heat you want to keep out, go for one of the more reflective tints (usually refered to as titanium or platinum)

I have the Llumar 35% platinum and it really makes a difference when entering the car after being parked in the equatorial sun for several hours. It is also not overly dark.
And I believe the Llumar tint carries a lifetime warranty.

 

I have Llumar 30% (not the platinum) and it looks good. It does have a little sheen to it.

 

To keep out the heat, Huper Optik works exceptionally well, however, it is not a dark tint.

 

Huper Optik all the way. If you are looking to block out heat and the sun's rays, it's the best. I don't like a dark tint especially at night, so the HO is perfect IMHO. Living here in AZ, it really blocks out the heat without the limousine-dark tint look.

 

Just don't tint the front windshield.

I just did mine, and it cracked in less than 1 week from the heat. The front windshield glass absolutely SUCKS. Worst quality of any vehicle ever made on this planet. And that's no lie.
