If you buy a car with money from a loan company and not finance from garage can u get logbook loan?

I bought a car paid with debit card for the full amount, the money came from a loan company, as the car finance where i bought car was expensive, its all in my name but finance in a relatives name, i pay the loan off by derect debit in his bank, i want a log book loan will the log book company know if thecar is on finance.
Answer
From what you said my understanding is that the loan is not secured on the car, the loan was not given in relation to the car, the loan company will not come for the car if you fail to pay the loan and if the car is hpi checked the loan will not come up, if all that is true then yes you can get a log book loan
