If you're about to buy a used car, stop! 1 in 3 cars have a history which you might not be able to tell. For instance, it could be an insurance write-off, could be stolen or perhaps it's registered as a different car altogether. HPI Check searches for the descriptions and histories of all UK road registered vehicles. Plus when you run a HPI Check you'll benefit from a National Mileage Register search, so you'll know if the vehicle has been 'clocked'. Avoid these common pitfalls and buy with confidence when you get a HPI Check today.
