Toyota is Trying to Figure Out How to Make a Car Run Forever:
Put together the best solar panels money can buy, super-efficient batteries and decades of car-making know-how and, theoretically, a vehicle might run forever.
That's the audacious motivation behind a project by Toyota Motor Corp., Sharp Corp. and New Energy and Industrial Technology Development Organization of Japan, or NEDO, to test a Prius that could revolutionize transportation.
"The solar car's advantage is that — while it can't drive for a long range — it's really independent of charging facilities," said Koji Makino, a project manager at Toyota.
[...] But the current forecast is only partly sunny because there's still some work left to reach that level of efficiency.
"This is not a technology we are going to see widely used in the next decades," said Takeshi Miyao, an auto analyst at consultancy Carnorama. "It's going to take a long time."
[...] Toyota has been testing a new solar-powered Prius since July, though it acknowledges that cars running nonstop without connecting to a hose or plug are still far away. Even so, the Toyota City-based company said the research will pay off in other ways.
Indeed, there have been some breakthroughs, mainly due to advancements by Sharp. The prototype's solar panel converts sunlight at an efficiency level of more than 34%, compared with about 20% for current panels on the market.
[...] If the car is driven four days a week for a maximum of 50 kilometers a day, there's no need to plug into an outlet, NEDO's Yamazaki said.
Or only drive it on weekends.

Have you heard of the wonderful one-hoss shay,
That was built in such a logical way
It ran a hundred years to a day,
And then, of a sudden, it — ah, but stay,
I’ll tell you what happened without delay,
Scaring the parson into fits,
Frightening people out of their wits, —
Have you ever heard of that, I say?

Good one--my father (from small town Maine) introduced me to the one-hoss shay as a kid, wonderful poem/story.
More recently (1973) a somewhat similar attempt was made by Porsche with their Long Life Automobile project -- designed to last in the worst salt/corrosive environments for at least 30 years:
