I had my 2010 Honda Insight for 5 years.
The gas mileage was around 40 mpg, and about 45 mpg on long trips.
I used synthetic oil in it since I bought it.
I never had any major repairs on it.
It was a great car.
It wasn't the most comfortable on long trips.
I never sat in the back seat so I'm not sure if they were comfortable.
My older friends had trouble getting in and out of the back seat.
But it was a nice car for the price, reliable, nice looking, and had great gas mileage.
