I've been looking for a used car for three weeks and i think i've finally found the one... I gave a deposit to the "owner" because it puzzled me a bit the difference between keeper and owner. However this link actually clarified to me the difference between "keeper" and "legal owner". I learnt from my last viewing that the keeper of a car isn't necessary the legal owner, since from where i'm from this doesn't happen (as far as i know) i got curious and i would like to understand how to check the real owner of the car, and if i can't if this information could ever be necessary when i've to sell/buy a used car. People suggested me to check if the car has been stolen or not, to check the HPI etc, but i don't get the sense to make such distinction between keeper and owner... So for future reference i would like to get a deeper sense on the subject.
