From my experience the companies providing these loans have moved away from simply contractually implying a lien over the asset.
At the point of taking the loan out two documents are signed -
1. A credit agreement
2. A Bill of Sale - which legally transfers ownership of vehicle for the period of the loan.
On this basis they can and will reposses the vehicle if payments are not made.
I have extracted some product detail below which actually highlights there process / T&C's.
Must reside in England or Wales
Must be at least 18 years of age
Must have a regular income sufficient to meet the repayments of the Loan
Must be the legal owner of the vehicle
The vehicle must be covered by a paid, fully comprehensive Insured Policy and have a valid MOT and Vehicle Licence
The Trade Value of the vehicle must be greater than £1000
The vehicle must not be the subject of any outstanding finance
Lend up to 50% of the Trade Value of the vehicle, valued according to Glass’ Guide.
The minimum value of a Loan is £500.00 (50% of the Trade Value)
Lender to retain the original V5/Logbook, MOT Certificate and Insurance Certificate.
The Loan may be repaid over any period between 13 weeks and 50 weeks. The maximum period for repayment is 50 weeks.
Early settlement of the Loan will incur an Administration Fee equivalent to 4 weeks of the Interest charged on the Loan.
Interest will be charged at 9.25% per month (APRs vary according to the repayment term and will be confirmed prior to execution of the Loan) As an example, a £1000 Loan with repayments over 24 weeks will result in weekly repayments of just under £65.00
Further Information:-
If the borrower fails to make repayments against the Loan, the lender is entitled by Law to take possession of the vehicle.
If the borrower fails to pay instalments at the correct time, a Reminder will be issued
If the borrower fails to respond to the Reminder within 7 days, a Default Notice will be issued
If the borrower fails to respond to the Default Notice within 7 days, a Termination Notice will be issued.
After a further period of 5 days, the lender will legally take possession of the vehicle at any time
Administration Costs in the pursuance of overdue payments, trace and recovery, repossession, storage and sale are added to the balance of the Loan and must be repaid.
Hope this helps......
