Does anyone have an opinion which of the available motors, up to n including 2018, would run the longest with least problems (normal maintenance on both?...the 1.4 turbo or the 1.8 normally aspirated. I value your opinion. There are a boat load of 1.4L turbo w/ 6spd on the market, In my mind, I wonder how long the 1.4 will last with a turbo, especially if the turbo is overused for the sake of performance at each stop light. The 1.4 is the same engine, in none turbo form, that is in the spark.
