Under the 2015 Consumer Rights Act you have the right to reject a car from a dealer within 30 days of purchase if your rights have been breached. This is called the short term 'right to reject'.

It covers faults that were present - or developing - when you bought it, or it was received in a condition that does not match what you were told. But it'll be up to you to prove that's the case. After 30 days you lose the short-term right to reject.
