For your mileage, we'd recommend a petrol or hybrid (full hybrid – not a mild hybrid like the Sportage). As you're used to a premium SUV, have you considered a Lexus UX? It's an impressive hybrid SUV. You'll be looking at a slightly older example within budget but it ticks all the boxes and, being a Lexus, will be extremely reliable. Alternatively, look at mainstream alternatives like a petrol Skoda Karoq or Volkswagen Tiguan. Both represent excellent value for money and make a sensible used purchase. If you're concerned about out-of-warranty costs, consider buying an aftermarket warranty.
