Easier to get parts... but cheap at the dealership? Hell no.

If you want to convince her to get a hybrid, go for the Prius. Honda's CVT-equipped hybrids don't have a stellar reputation secondhand, due to issues with the CVTs and battery packs. Best bet is to get a manual transmission one, but I don't think that's what she wants.

The Prius, apart from the odd electronic niggle (covered by warranty), is one of the most durable and sought-after secondhand cars on the market. The battery packs are guaranteed for eight years, but they've been proven to last longer than that, and those I know who deal in secondhands have nothing but praise for the Prius.

The Prius requires less brake pad changes than any other car. It requires fewer maintenance stops (since the engine isn't always on). It is good on gas and has a very good range, especially if she takes it easy on the highway. Interior space is immense and the trunk on the 3rd gen will satisfy her need for crossover-type space. And while it may cost more up-front than your regular car, the price premium in the US isn't as bad as here... her budget will definitely get her into a new one. (just don't go nuts on the options)

The bad points? The interior plastics are not that great, and the gimmicky center console feels flimsy. Cornering grip is not that good, either, but your sister probably isn't Michelle Baumgartner (or Danica Patrick) so she won't mind. At least the car is stable, neutrally balanced and comes with stability control. If she wants it more sure-footed, there's the 17" option wheels and tires... but that will cost extra.

Yes, it's expensive for a small car... but thanks to the update, the Prius is more of a tweener now than a compact, and legroom and elbow room are at par with your common CR-V or RAV4 crossover. And the resale value, especially in these gas-strapped times, is incredible. Heck, she might even want to bring it back home when she's done.

Another practical choice would be a secondhand Prius or compact car, but prices of secondhand economical cars are on the rise in the US, so bargains may be hard to come by.
