Is car finance the best option

Can I cancel Finance Welcome Car Finance, after a few days?

Hello, I bought a car from the "Welcome Car Finance" and after talking to members of my family and friends, I decided I no longer want the car I also feel that I'm a little broken with the amount you pay monthly and I do not I will be able to do, he bought the car anyway on funding, there are only a few days, there is a notice period that I am authorized to return the vehicle and cancel the contract without penalty seriously?

I guess they're in the UK, where a case of these laws apply May 2: View. If you have purchased on the Internet there is a 7 days you can cancel. Otherwise, it may be a period of 5 days (depending on where the contract was signed with them).
