Do you think car salesmen will disappear with the Internet? Specially in new dealerships.?

No - if anything, Internet shoppers make up 50% or more of the business in a dealership and dealers are striving to better market to and manage their Internet shoppers.

Clients will always want to drive, smell, touch and see their car before wiring money to a bank and having it turn up in their drive away. If they are trading in a car, someone is always going to need to appraise it in person. You cannot evaluate condition and the value of someones current car over the internet or via email.

The manufacturer does not want to get involved in any of these details when they can simply make the cars, sell them to the dealership (giving the manufacturer all of their money with none of the pain) and letting the dealer handle the details.

i think possibly in time like say in the next 10-30 years because everything will be replaced by computers some day.

Nope..............
