It died last month on February 10, 2015, after 174,000 miles, avg 43 mpg, 7 months short of it's 10th birthday.
Cause of death:
A failed ignition switch bricked the vehicle without warning- no more turning the key, therefore no start, no test drives, no dash lights to read the odometer. $700 projected cost of repair, plus towing. I finally was able to arrange a sight-unseen $500 off site trade in value from a Toyota Dealer toward a new Corolla LE Eco (rated 42mpg highway).
- It had been still running great, getting 42mpg on a 300 mile trip the day before.
- The hybrid feature had been showing idiot lights for 25,000 miles or so. Apparently, this isn't much of a problem.
- Battery repairs were quoted at about $3000, more that the estimated value of the car.
- One brake job at 120,000 miles, 19 oil changes, 5 CVT fluid changes, some tires, and that’s about it for maintenance.

Hybrid Cost/benefit analysis:
Extra Hybrid Costs: $ 2200 at purchase, Add’l CVT service vs std automatic $300, lower trade in for vehicle with perpetual idiot lights $1500 = $5000 Total.

Gas savings: 4375gal in a 40mpg car instead of 5833gal in a 30mpg car for 175,000 miles at $3/gallon is a savings of $4375. But we used to drive 30,000 miles per year in 20mpg vehicles before we got the Hybrid. So, we could look at this as the Hybrid miles as saving us 4375 gallons or $13125.

Why I didn’t buy another Hybrid: I paid for the hybrid both at original purchase and as a discount on trade in value. Even with 175,000 miles of use, the return is marginal.

Why I bought a Toyota instead of a Honda: I’m sure all old cars have their issues, but being stranded by an ignition switch is awkward and potentially dangerous, even after 175,000 miles. Besides, my wife liked the blue one.
