I have owned several silver cars over the years. The color hides dirt better. I remember a joke on the Audi TT forums that silver was the fastest color. So I bought a silver TT. Was it faster...physiologically I thought it was.
I have a few weeks to take delivery of a silver M3. My wife has the midnight blue model x. I like that color but did not want two cars of the same color. White is such a common color especially with all those transit vans and commercial work vans.
Taken from an article online....
Researchers had two cars in the sun for an hour, one black and the other silver, parked facing south, in Sacramento, California. The silver Honda Civic (shell SR 0.57) had a cabin
air temperature of about 5-6°C (9-11°F) lower than an identical black car (shell SR 0.05).
A silver (or white) shell would allow for a lower-capacity
air conditioner as well. The cars were run through five identical cycles of soaking in the sun. Each cycle consisted of an hour with the air conditioners off, followed by a half hour of cooling with the air conditioners running at maximum. The researchers measured the roof, ceiling, dashboard, windshield, seat, door, vent air and cabin air temperatures in each car along with weather conditions in the lot.
Another funny article stated what the color silver says about you....
The metallic gleam of silver shines bright with innovation. Think stainless steel appliances and silver technology. It's the color of security and style.
A silver car color indicates that you're a high-class lady or gentleman with an eye on the upscale. Your status is higher in the world, and you're not afraid to show it.
