If you all don't mind me interjecting for a moment... (and even if you do mind, since I am a mod)...
What I feel Deluke was saying is that there are a lot dealers and/or salespersons who are not well informed about many of the particulars of the products they are selling. Like it or not, this is true. Salespeople are just that, salespeople. They are skilled in selling automobiles to potential customers and closing the deal. However, most customers are not as demanding of the kind of product knowledge and details that big enthusiasts (such as those that gravitate to internet forums) generally demand. Many may not even know where to find certain information on an individual basis. Why? They generally do not, or never have really needed the info to close the deal.
I have to tend to agree with that. Most dealers I have been to do not have a lot of people on the floor with a lot of detailed, intimate knowledge of every vehicle there. They know the basics, the stuff to get Joe Customer into a Queen Size Family Truckster. It just is what it is... Doesn't mean all dealers are not all that helpful? No. Also, does it mean they are all extremely helpful and knowledgeable? Again, no.
However, what I really, REALLY cannot understand is why everyone is degenerating this thread into a flame war, which is the real reason I posted. People are making this issue personal, and there is no need for it. It is also against the rules. Just discuss the facts please. We can all respectfully disagree with each other without throwing around barbs and attacks, or going out of our way to get under people's skin and cause trouble. Thank you!
