I'm seeking a reliable hybrid (possibly electric) SUV 4WD that is sufficiently comfortable, economical and powerful to use chiefly for lots of 600-mile journeys on motorways. I don't really know where to start. Should I go for an older Porsche Cayenne, a Honda CR-V, a Kia Sportage, a Range Rover Sport? I don't want an Audi or BMW but would look at anything else. I could spend £30,000 or more but would prefer to compromise a bit and spend closer to £20,000. Ideally, I'd want to be able to sell it again having put 30,000 miles on the clock in four years time for a decent residual value too. Your advice would be much appreciated, please!
