Seller won't provide location details.

Hi community, help please.

Have just won a bid on a vehicle.  I am trying to arrange a bank transfer, however to set up a new payee in my account I need their location (street address).  The vendor will not provide either their phone number, nor their street address for vehicle pickup, and are insisting I do a cash deposit into their account to purchase the vehicle.  They will not accept cash on delivery.

It is screaming :"scam" to me, I am afraid that if I make a cash deposit into their account, without them giving me their location details (nor phone number), they will just disappear without anyway of me contacting them. 

Advice greatly appreciated!

Thanks
