Used in business and signed. Have had several calls on the phone from people just wanting info about the car. ;) We love the car and for running around checking out real estate its great.
Most agents try to impress their clients with the big SUV or BMW, MB, etc. but we just want to do the best job possible and work hard for our clients. Most of the clients just want to follow and the few times that we need to take more than one in our car we use the 300M which isn't painted or signed.
It does get attention and the clients that follow in their car haven't had the problem of loosing us in traffic.
