My wife and I are considering to buy a car, but most of our trips will probably be around 2-4 miles long (drive a kid to school and back, stop by a supermarket). And, maybe, one longer trip once a week.
We were looking into getting a Mazda 3, but it has a direct injection engine. And direct injection seems to have a reputation for eventual carbon build up if used for short trips (or with other bad driving habits). So I also looked into getting a gas Toyota Corolla. Supposedly, it has a "direct injection with port injection" engine.
Question: is port injection preferred for our use case if we would like to keep a car for 10-15 years?
We are first-time car buyers frustrated by the amount of options to consider, so any perspective would be helpful.
