My wife and I have a 2015 Ford Kuga, which we are looking to replace it in the not too distant future. We enjoy the ride height and the practicalities of four wheel drive and we do not want an electric car or a plug-in hybrid. At the moment, we've been used to a manual gearbox but are aware that auto boxes are more prevalent. We don't cover as many miles as we used to, probably about 10,000 miles a year, if that. Does this negate the use of a diesel?
