All in all, the Insight has done well as a commuter car. I commute 88 miles each day. Gas has been great. According to advertisements, I should be getting between 62 and 68 mpg. Reality-I get on average 58 hwy & 52 city.
Warning! I fell into the California clean air trap. According to California DMV, the Insight DOES NOT qualify for carpool status for clean air vehicles. Unfortunately, California made that a rule in 2000 and didn't mention it to dealers still promoting this perk.
