That's actually a really good idea. I'm sure they have all sorts of sales reports they have to full out which no doubt are in different coloured books so they can provide feedback to HQ about how things are going.
If 967 people came in a test drove one and then went and purchased the same other car M-B would have to pay a consultant to come in and explain why.
Considering I actually have a bit of respect for M-B A I think they would actually listen. As opposed to LRA which would, well, not.
