Ethical Dilemma

I came across an ethical dilemma that fits in perfectly with one of my portfolio review assignments. We are working on getting our foot in the door with several European auto manufacturers. I usually produce samples with our visitor’s logos, and did this for BMW when they came in last Wednesday. BMW stayed late, and Thursday morning I was doing testing, so when Audi came in I still had their samples in plain sight. They seemed very interested in these, but no one addressed the issue. My dilemma is - should we have clarified that we are not currently producing parts for BMW? I feel that by having these samples in sight we might have implied a more substantial relationship with BMW than we actually have.
