Seems a bit weird. The links just email him, so that you can apparently be added to the 'pre-approved bidders list' ?
The guy should have listed with a buy it now option, if that is how he would like to sell it.
Also says he can't receive messages sent thru the ebay message system. Seems bollocks 'cos they are able to be read directly from the ebay message system in 'MyEbay'.
His English is also shite.
Maybe his account has been hacked and the hacker has listed the car and it is a scam.
