I'm surprised to hear that you're finding insurance prohibitively expensive on your Sportage – although I suspect age is a factor here. Do try shopping around for insurance quotes (if you haven't already) before you commit to changing your car. This page might be helpful: www.honestjohn.co.uk/cheap-car-insurance/

If you do wish to replace your Sportage, it's probably worth looking at smaller SUVs. The Toyota Yaris Cross could be a good choice – it's a very cheap-to-run hybrid with plenty of interior space. You can find more of our favourite small SUVs here: www.honestjohn.co.uk/guides/best-small-suv/
