Most impressive car we have owned

Jake, 05/18/2018
2018 Buick Regal Sportback Essence 4dr Hatchback (2.0L 4cyl Turbo 9A)
We have had this car for over almost 3years now and there is very little not to like. In terms of value, it seems to beat the big name imported cars hands down. It has a responsive and peppy engine. The instrumentation is logical, though somewhat understated. Mileage on the highway has been much better than expected. We averaged over 30 mpg on a recent 500+ mile trip. Driving comfort is … very good. We did have some mistaken potential crash warnings from the crash avoidance systems, especially when making sharp turns at an intersections where we turn into a lane that has a large truck stopped in the turn lane of the street that we are turning into. Wish lists: The car had an automatic closing mechanism for its hatchback opening. The navigation system could be much more user friendly, like the systems offered by Tom-Tom for it's GPS units. GM should really update this as I think this could just need to be a software update. The memory system for who the driver is for seat positioning, sometimes seems to relate to whoever entered the car first, not necessarily to the driver. This could use some tweaking. Likewise with the recognition of which phone it should pair with. Again these might also be a software tweak. The most annoying thing is the key fob’s emergency alarm . It seems to go off easily with any mild pressure against anything when in one’s pocket. Sold after 5 years. Was a good, very reliable vehicle.
