You may struggle to get something nearly new for that money.

A good starting place would be to consider if you you'd like petrol or electric. Used electric cars are cheaper than their petrol equivalents at the moment (and much cheaper to run if you have a charger installed at home - these cost around £1000 if you need to get one fitted so you can factor that into the price). We've found a 2024 Mazda MX-30 with just 4000 miles for £13,700. It only has a range of 124 miles which is not a lot, but if you're not doing long journeys and can charge at home, it could be a good choice. We'd also suggest looking at the Vauxhall Mokka (which has a 200+ mile range) but it would likely have a higher mileage.

If you want petrol, look at a Hyundai Bayon although for £15,000 you may have to go for a 2023 car or a 2024 with higher miles.
