The Kia Carens Clavis is the best pick for you. It's an easy-to-drive MPV that offers comfortable seating for 7 passengers. Given your usage, we'd advise you to consider the Clavis with a petrol engine. The standard 1.5 naturally-aspirated petrol engine will be sufficient for your requirements. However, your budget allows for the more powerful turbo-petrol engine, whose added performance will come in handy, particularly on highway drives. The turbo-petrol is available with a manual gearbox, and you could also consider the dual-clutch (DCT) automatic variant for more convenience. To keep within your budget, you'll have to opt for a lower trim version of the DCT automatic, though.
