Hi Tony, I’m sorry to hear you are having problems trying to buy a car.
It is likely that your wife is being refused car finance due to her being on a debt management scheme. How long has she been on the scheme for? Has she fallen into further arrears in the past 12 months?
Credit profiles can change and sometimes do quite quickly (in both directions). If she continues to meet payment requirements going forward, she’ll improve her position but, as you say, there is a risk of her damaging her profile further if she keeps on applying for finance and being refused.
Without all of the information, it is hard to advise but I think I would suggest keeping up with payments over the next 6 months or so and then applying for car finance.
Give us a call if you’d like more advice, or you can find some good advice – HERE
Best of luck.
