There are many selling sites ...Ok I will share my experience...I will give the general tips instead of giving you a particular site...
first do a Google search and find website that has the car that you desire
pick a legit one from it...
To check whether a site is legit usually, I do follow a simple checklist to see how well they do, especially when I need to part money with the site;
1) Does the site have a current SSL certificate?
2) Use http://www.whoisxy.com/ to check the whois information and check whether the contact information matches with the one in the website.
3) In the domain contact details, is there a valid email address.
4) Is there a valid phone number visible, and does it work ?
5) Go through review about them using Webutations.net and check whether they are scam free.
The most important thing you need to have if you want to make payments online is your credit card. In Ghana, they can’t be called credit cards, they are debit cards. These cards are directly linked to your bank account, whatever payment you make is instantly taken out of your bank account. These cards are not the regular ATMs cards the banks have been given us. Though they look the same, these cards are special and won’t be given to you unless you ask for it from your bank.
Some banks in Ghana that I know they offer these cards are UBA Bank (they card I’m using was provided by them), Ecobank, Barclays Bank, Standard Chartered Bank, Zenith Bank, Access Bank and Gtbank. These are the few banks I know in Ghana that provide this service. The charges and limit of usage depends on the bank you want but so far, I love the service I get from UBA bank. I applied for the card which cost ¢10.00. The card arrived in 3 weeks time and since then, I have been using it to make payments online. Payments are calculated using their foreign exchange rate to convert whatever item you paid for from cedis to that currency. It’s so simple, now I don’t worry about how to buy a phone, laptop, get a web host, buy domains, etc online. I can do all this with my internationally accepted debit card.
Another area you must know is, 30% of online merchants and shopping carts won’t accept cards with Ghana as it billing or shipping address. Sites like Amazon won’t allow you to use your card here in Ghana to buy anything from their site. But there is a way around this. You can go to buyusaquality.com or myus.com and register. Get a US address and anytime you shop online, use that as your billing and/or shipping address. These are two examples of companies that act as mail forwarders. They will receive whatever you bought online, charge you a fee depending on the weight and postage charges of the package and forward it to you. There are many mail forwarders companies out there but these are two I am familiar with. You can try the services of the others. Just go to Google and search for ‘USA address’.
Be careful not to share your card details with anyone. It is also advisable never to save your card details online. Please, don’t use your card at public computers. I will advise you to use your card on your own computer. If you want to make payments on a public computer, please after the payment, look for the browser history settings and clear the cache, cookies and browsing session. Do this to ensure no one hacks your card and spend the money on it.
There you go. If you want to make payment online but didn’t know how, this is the solution. Walk into any of the banks mentioned above, I recommend UBA and get yourself an internationally accepted card for making payments online. This card can also be used to make payments at POS and withdraw money from ATMs all over the world.
Again a simpler solution on how you are going to pay for your car online is this. Due to a lot of credit card fraud in Ghana, A lot companies do not accept credits card s from ghana.
But some banks like Gt bank has a visa card that is accepted internationally online. Also paypal has ban ghanaians from registering for their service so you can't just register for a paypal account right away. On Other hand, you can get a verified paypal account or verified credit card that can allow you to make payments online at popular sites like amazon at http://vccghana.com. I have personally used their service and i know the owner of that website personally so for online payments, you can visit them at their office at achimota or call them on 0243463595
The nest question is how you are going to ship the car to ghana. Does the website you are buying the car from offer shipping?. if yes then you just need to provided your correct address otherwise, you will have to find a shipping company to handle the shipping for you. visit http://www.autosghana.com/shipping.php and http://ghana.shipping-international.com/auto-shipping/ to help you your shipping if you any difficulties.
Once you know how to pay and how to get it here, you are good to go.
