Put SOMETHING in it other than a hybrid and you may get similar performance and costs without the complexity. It may be trouble free for you, but not for all, and complexity equals vast amounts of engineering and manufacturing costs. I'm just thinking out loud on this one…Prius won't be on my list regardless of engine.

When you feel it's time to get rid of the Prius, maybe time to consider a Volt?
Consumer reports recently did a cost of ownership per mile showing the 10 best and 10 worst in terms of actual cost. As expected, Prius is one of the best and Mercedes is one of the worst.
As for the Prius complexity, the consensus within the Prius community (and outside from what I have read) is that it is an extremely reliable car with extremely low maintenance costs. The engineering has more maturity than any other hybrids on the market and it continues to sell like crazy. Prius owners buy another Prius when they get rid of their cars... Both new and used Prius cars are becoming the taxi of choice in many markets.
The failures I have had on my 2007 include a water pump replaced under warranty and a failed tire pressure sensor not replaced under warranty. That's it. Ooops, the NAV unit crapped out and that I replaced with one from ebay. One fairly expensive (under $1000 maintenance at 120,000 miles, other than that, oil changes. I think the brake pads are original. I'm probably on my third set of tires.
The Volt just screams everything I hate about detroit. Too little, way too late, and can anyone really have any faith in General Motors...? I work at JPL, we recently had an energy-efficient car show in our mall area with owners bringing their cars and manufacturers providing spec sheets and incentives.
You are correct that the Volt gets a big tax credit. When I bought the Prius in 2007 I didn't get a big tax credit because it was based on income at that time. But I did get a carpool lane sticker, which at the time added about $5000 to the value of a used Prius. If you get a new electric or plug in hybrid in CA you get a carpool sticker a while - there is a limit on the number. The hybrid stickers expired a year or two ago.
So at the car show at JPL there was the following:
Volt: Nothing says plastic more than a General Motors dash. Years late to the game. Promises were made...
Smart Electric: For almost the same money you can get a Leaf, which is pretty much a real car. The Smart electric has the same problems as the Smart, except without the horrible transmission of the gas car. Too much for too little.
Leaf: Nice. Comfortable. Great choice. Great tax credit, but that will probably end soon for Leaf since the credits are limited to a certain number from each manufacturer.
Fiat 500: Amusing, being tested in the California market.
Plug-in Prius: Interesting only because you get a carpool sticker, otherwise it's just a longer range Prius. And if you get the tax credit on this it would be the bargain in the collection.
Tesla S: What's not to like about the Tesla !!!!!
