I drive about 3000 miles a year and have always owned normally-aspirated petrol engines with torque-converter gearboxes. I'm wanting to buy a replacement but seem to have little option other than a turbo engine and/or a non-torque-converter gearbox. I've looked recently at a Ford Kuga which gives me a 1.5 petrol turbo engine and a torque-converter box and a Mercedes GLA which gives me a normally-aspirated petrol engine and a 7G-DTC gearbox. Leaving aside other differences, which of these configurations is likely to be most reliable during a 12-year-or-so ownership, please?
