I prefer not to talk to the sales until there is a reasonable chance that I
will actually buy. I might be preparing a bid, I might be preparing
proposition for the management, I might be developing an idea and trying to
find out if it makes sense or not, I could be doing several other things,
where knowing a ball park figures is essential, but talking with sales is
step too much, and often causes completely unnecessary preassure and
exposure from sales.

Second reason is that when prices are not transparent, one gets into the
situation very similar to buying leather jacket on Istambul Bazar. Any bit
of information you can have before you engage in conversation with the
eloquent gentleman can help to reduce your missery at least a bit.

Do I have application where I think VW might be suitable or even maybe
needed? Yes.

Do I prefer to talk to their sales completely unprepared and clueless? No.

Will I actually buy something? Depends on many things, price beeing
important one.

So if you have some information that you are willing to share, I will be
truely thankfull to hear it. And I will contact sales (or maybe allready
have, or never will) when I feel ready for that, and when I choose so.
