Can you live with one car instead of two? Sell one now, and put the money straight into your house deposit account. Or change the £25,000 car for a £10,000 one, and deposit the difference. Also, if it’s a mile from home to work, don’t pay £20 a week in bus fares or all that cash on car parking fees. Walk. Or get off a stop earlier, or park in a cheaper place. Then walk. It’s good for your health/weight/back too.
