I don't like the ones that don't answer emails.
Email is really the best of both worlds-
1- your conversation can be conducted at the lesiure of both parties.
2- you have an automatic set of notes to refer to in the future (what did he say the 5th VIN digit was?)
3- it's much easier to ask additional questions which everyone always thinks of as soon as they hang up the phone.
4- no background noise
5- gives both parties time to think of their questions and their responses.
The list could go on, but those are some of the main ones.
If you don't return my email, you are potentially missing a sale to a cash buyer.
Sure, if I want it bad enough I'll try calling after a day or two of no email return, but by then you may have sold it for less than what I would have paid.
