I am looking at buying a car from used car sites limited but I am not shire if it is a scam or not

Check their contact information, payment details and physical location.

Holme, what is the website for the "used car sites limited" that you are speaking of? I googled it and found many.

Hi the web address is www.carssalesltd.com many thanks

Not fake, but very rubbish.
You'd be better off looking elsewhere.

Don't buy online, go and physically look at the cars. Have a respected mechanic you know check them out before you buy. They listed a physical address, so drive down and look in person.

Its simple just call them and ask them for their address and if they are real than they should have a postal address

Many thanks for your comments, I have found out that the company is real but the web site www.carssitesltd.com is not they are now being investigated by the police so do NOT buy from them they are using the name to scam people, thanks again
