It's amazing how many web sites that cater to high end customers ignore
email requests.

Consider that they may have a very low proportion of genuine inquiries,
even after spam is filtered. It is difficult to qualify prospects who
initiate email. It isn't like a walk-in dealership where you'll be sized
up at a reception desk and matched to an appropriate salesman. For all
they know, you're a Moldavian beggar.

But you're right that they shouldn't completely ignore email, if they
solicit email. Likely the Web site was designed by an outside firm who
didn't appreciate that the firm was not fluent in email.
