Marketing onlineOnline marketing advices

I’m trying to buy a car, and the owner of the car im interested in is in UK. here is the deal. he will send me the car to my address.but, I must be making an online payment through ebay motors, i’ve never done such transaction through the internet. and i dont have any idea how much safe that is. I need overall advice what the important things I should do to deal with this deal safe.
agin, the deal is :
1- making deal through ebay motors.
2- shipping the car to my address.
3- inspect the car for 10 days and then give the final word wether
i want to keep the car or give it back to him and get my money back.
how to make sure this car is not stolen or something.
the thing that worries my is that the price is VERY low comparing to the market even though, I hve checked the car history and every thing was just fine. the price was a helf of the market rate.

please help my guys.

I’m looking into buying a new Nissan Versa and am looking at local dealerships websites. One I found show the MSRP price as well as an internet price for all the Versas listed. All the internet prices all $2,500 to $3,000 cheaper than the MSRP price they have listed. So I wanted to know what does the internet pricing price tag mean and how does it work and can if I can really get the car that much cheaper how do I go about the process? Thanks.
