Owner is confident there are 4 previous owners. I've emailed HPI provider but I'm picking the car up on Wednesday (subject to inspection) so I doubt I'll get a response before then. With it saying 0 previous owners does that mean the car isn't registered??
Have a look at the V5 registaration doc, but TotalCarCheck is not actually HPI (only HPI is HPI) TCC costs £2.90 HPI is £20 which may explain why the TCC results could be a bit off?
