I have to admit, it is one of my (and there are a few) pet peeves on BAT. A dealer is a dealer, there are dealers on hard surface sites all over the country who only take in consignments and they have to register as dealers.
If you are taking profit out of selling cars on a regular basis, you are a car dealer. I know all states are different, I think WA may be more than five cars a year, which I think is pretty fair, less than that is fine, you may change often or you do the odd favor for a person not internet literate.
i will add, as Dick refers to above, and has been proved again and again on BAT, the dealers don't know many or sometimes any of the cars they represent and isn't that part of what BAT was about on the buyers side, being able to communicate with somebody who really knows the actual car ? Sadly, no longer, as it really has become a dealer site, if you look now there is very small percentage of true "private" sales, dare I say 80-90% either on consignment or purchased recently for resale.
As I mentioned on the current Batmobile sale, not only do the dealers selling not know about the car, but when they get even a modicum of correction on their claims, their jerk circle of dealers come on in force, again not knowing the car, but drowning out a potential informed voice on said car.
To be clear, I have no problem with people making profits, in fact I applaud it, especially if they are doing a good job or supplying a a good service.
So for fairness, i think dealers should be identified, not only when selling, but also when commenting.
Just my 1.5c on the issue, as its not worth 2c
