Anything i should know?.. do i need any specific papers and to make sure i don't owe somone else's fines. also the hpi textcheck-any codes that'll come up or any warning signs for a car being written off i should be aware of?
Do not take this the wrong way but the subject is so huge and starting from your clear lack of any idea, I think it would be outside the scope of an AB answer. Have you got a more experienced friend you can take along?
one thing to check is to make sure that the vehicle has no "interest" in it. This means that check that the vehicles does not owe any money on finance. Do a hpi check online.
