If you're worried that a car you're thinking of buying has been in an accident, there are a few things you can do to check. The first thing to do is look over the bodywork for any signs of damage. This could be anything from scratches and dents to mismatched paintwork. If you spot anything, it's worth asking the seller about it. They might be able to give you a perfectly innocent explanation, but if they can't or won't, it could be a red flag. Another way to check is by looking at the car's V5C document (also known as the logbook). This will have a section called 'notifications', which will list any changes made to the vehicle. This could include anything from a change of colour to the car being declared an insurance write-off. Of course, none of this is conclusive proof that a car has been in an accident, but it's definitely worth doing your research before handing over any money. A comprehensive history check, however, will tell you what you need to know.
