Jargon Buster

• What are my rights if a used car goes wrong?

  It depends heavily on whether you bought from a dealer or a private seller - dealers carry far more legal obligation.

• Can I return a used car to a dealer?

  Within 30 days, generally yes if it's faulty - but changing your mind isn't the same as it being faulty.

• Who do I complain to about a car dealer?

  Start with Citizens Advice, who can refer serious cases on to Trading Standards.

• What is the Motor Ombudsman?

  An independent dispute resolution service for the motor industry - but only for businesses signed up to its code.

• What can I do if I bought a car with outstanding finance?

  UK law gives some protection to private buyers who didn't know about the finance, but whether it applies depends on the details.
