I'm ok with a dealer letting us know about a car they have for sale. I think if the forum were a lot busier and we had a lot of dealers trying to sell cars it would be a problem but that isn't the case.
In the case of a 182 a lot of people have had long waits to get one so finding out that a deal has fallen through and one is available could be quite handy for someone in the market.
I'm cool with things how we are now but if it gets out of hand we can just put a sticky thread up on sales etiquette, whats allowed, what isn't etc
What I would like to see is offers of discounts on spare parts, aftermarket stuff, accessories, servicing etc for members
