I am tentatively thinking about changing my car. For work purposes I could do with a large people carrier or minivan, but if I were not childminding I would prefer something a lot smaller and more economical. I wonder if anyone has experience and can advise me on whether I could claim any car purchase expenses, loan payments or lease purchase payments as CM expenses. If so, what happens if I either later sell the car or stop minding (or both)? Is there an idiot-proof guide to vehicle expenses and childminding? Do I need an accountant?
