Is there something special about that engine? I'm thinking of getting a Subaru.
It’s horizontally opposed, which means it is more balanced than a typical inline four, and it also creates a lower center of gravity in the vehicle which helps with handling, particularly in potential rollover situations. It’s a well engineered, stout little engine that can make a lot more horsepower than factory tune, so it’s very popular in road rally cars, and very popular with the tuner crowd here in the US.
One note of caution, if you’re looking at a turbo model, there are a few things that you should and shouldn’t do. If you’re looking at a used turbo, the maintenance habits of the previous owner are important, to the point that I’d not consider one without verifiable records or factory warranty remaining. Get full synthetic oil in it as soon as you can and absolutely do not ride the oil changes. The design of the turbo is such that if it throws a bearing you’re potentially looking at a new engine, the debris will not be isolated. That said, a well maintained one is a joy to drive, I have one, an ‘07 2.5 turbo. I love the car.
If you don’t need or want that sort of acceleration, go with the normally aspirated models, they’re about as bulletproof as you’re going to encounter among new models.
Or, if you want somewhat improved power without the turbo, they make a boxer flat six as well, 3.6 liter.
