I have 168,000 miles and have only done regular maintenance on this vehicle. The brakes haven't been changed in 130,000 miles and still have half the pads left. Only issue I have had is the window rubbers have dried out and need replacement. $220 cost for replacement. Not an issue with the value I have received with this vehicle.
This has been, without a doubt, the least problematic car I have ever owned-- and that includes five Hondas. It has had ZERO defects, has never needed to go back to the dealer and has been dead reliable for 140,000 miles so far. The paddle shifter option is stupid for a car focused on gas scroogers, as is the tach with the CVT transmission. They could have eliminated that stuff and put in a back-up camera, which the car desperately needed. You can't see out the back worth a darn. The seats are not very comfortable, but other that the sport seats in a couple of sportier Civic hatchbacks I've had, no Honda seats have ever been very comfortable to me. Interior trim has been robust but is hard plastic and cheap looking. Economy has been better than expected. A light foot and highway cruising can get you up into the mid-40's MPG. Now depreciated, the second generation Insight would make a great used car value.
It was down to this car or the prius for a work car, I would pick this car. If you have to go through long traffic jams the Prius might do better but for overall value, but it drives great until need to pass on the highway.
The car handles very well, the hybrid technology in the car itself is quite impressive. The only issue I have with the Insight is the amount of room in the backseat for passengers is cramped, and the blind spots in the car are something to note. Other than those two discrepancies, I find the car's fuel efficiency and its ergonomic design very strong selling points, and Honda never ceases to provide excellent services to their customers as well as make great vehicles.
