If you're buying a used car from a dealer, they should be able to provide you with a service history. This will tell you when the car was last serviced and what work was carried out. If you're buying from a private seller, it's unlikely that you'll be able to get hold of this information. However, there are other ways to check a car's service history. For example, many manufacturers keep records of their cars' servicing online. You can also check the MoT history of any car that's over three years old. This will tell you if the car has failed any tests and what repairs were carried out. To do this, you'll need the car's registration number and either the make and model or the V5C document reference number. You can then search for the car on the Gov.uk website.
