Accepting funds from abroad.. whats safe?

[Colinevan]

I may be selling one of my cars, and the buyer wants to pay via bank transfer.

What i'd like to know, how safe is it for abroad and how long does it take to transfer ( i.e it may show as received immediately but make take 7 days etc.)

Is paypal much safer. I remember stories of people selling items, and upto 6 months later, the americans could claim that on there credit cards linked to paypal, they never received the goods, and the banks just remove the funds.
is this still true.

Buyer also wants ups to collect the car from my address, as he has an account.

Just want some peace of mind.

Thanks guys.
