Every dealership that I've talked to for the past 5 years or so has had one (albeit, typically the "department" is one person at the dealers around here).

All the dealers in my county have websites with an email address or web form to contact them. After doing some research on models, pricing, etc. I sent an email to each dealer describing what I was looking for and requested a quote. Some did not reply at all. I took the most decent offer. They dropped it off at my office. I never set foot in the dealership for the whole transaction.

When I lived in Waco, the Hyundai dealership's website's "internet sales" department was a page telling you to call Lisa at [telephone number]. No, I'm not kidding.

Apparently, they've wised up since then, because the link doesn't work:
