Website sale on GoDaddy?

[steven55]

I was looking for a domain for sale on Godaddy.

It has a proper established site on that doman name.

When the owner sells such a domain on Godaddy, is he selling the website too ?

Also I see a Trademark on that domain name, if someone buys such domain will he not land into trouble for that ?
Does anyone have experience of buying a website on Godaddy along with domain ?

Thanks
