Are you not including the finance with the blessing of your IP or are you just not going to mention it? There may be T&C's in your finance agreement that precludes you from being insolvent. You need to check this. If this is the case then your finance company can terminate the agreement and require you to surrender the car and then you may have to pay a penalty amount!
You have less than no chance of getting further finance for a car once all the paperwork has been signed off and the IVA starts.
Last Payment made 04/12/14. Completion Certificate 25/7/15. IVA company GT. No Issues
If it has been excluded as long as payments will be included once finance is completed, I don't see a problem

The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.
