Correct.  OTOH, Subarus usually have full-size spare for just that reason.  Given the constraints about differences in outside tire diameter/circumference, the full-size spare will be OK until your earliest opportunity to get a new tire, and have it shaved, of necessary.

All the above is true (2005 Forester owner) 107K miles.  Then again, most of the abovementioned items are well-worth doing on all cars.

Subarus used to have rubber timing belts, and since the engine is an interference type, it is absolutely essential to change the timing belt before it becomes questionable.  In my many trips to the junkyard, Almost every Subie there was because of blown engine, and that was almost certainly because of failure to replace the timing belt.  Hondas are crashed more often, it seems, but their engine design used to include interference engines with timing belts, and there are quite a few also junked for blown engines.   

As to OP, I think that I would try to find a six-cylinder Subaru.  Slightly more HP and considerably more torque than the turbo models, with less initial cost, and less maintenance costs. 

Usually available on the upscale models only.  I strongly suggest the sixes.

In my experience, most modern Subarus have the wiring harness already installed that is designed to accept a ton of plug-and-play Dealer-installed accessories.  Sometimes you can get such accessories from a junkyard for dirt cheap.  I've saved a ton of money upgrading my Forester with junkyard accessories.  For example, free key fobs (just re-program them), $5 Dollar auto-dimming rearview mirrors with compass and HomeLink, and some other things.  From Dealer, key fobs are at least $50, and the autodimming rearview mirror is way over $200.  If you do your homework, such as looking at parts numbers for particular accessories, some Sub accessories for multiple models and multiple years.  You will need to find a local junkyard that will at least let you walk around their yard and inspect vehicles.  Better yet, find a junkyard that will let you remove stuff.  For the owner of most any car, this is something of great value.

OTOH, there are places like SubaruOnLineParts that will sell Dealer-installed OEM Subaru accessories at considerable discount--they even have sales.  Most of these items are pretty simple to install, even for the DIY type, and almost all come with full instructions.

I've bought a few items there. The sub-woofer kit for my Foz added a whole new dimension to the sound, and along with the replacement radio, and Tweeters snagged from a junkyard donor, transformed the sonic experience.  The sub-woofer was plug and play, and the instructions were good enough for a total install time of 1/2 hour.  Install the second one on a friend's Foz took me 15 minutes.

There are many Subaru-oriented web sites.  I suggest looking around for one that focuses on six-cylinder Subarus.  In the meantime, subaruforester.org will be a place to start.

The fuel mileage is a bit less on the six-bangers, but not as much as one might think.  I believe the final drive ratios are higher for the sixers, as compared to the Turbos, which are geared lower for low-end power and acceleration.  It is not unusual nowadays to see six cyl engines outperforming fours with respect to highway fuel mileage.  It's all about how the final drive is geared.  with six-cyl engines, they have enough torque to be geared lower (better fuel mileage) while the engnes still have enough torque to get up and go.  It's all trade-offs.

As regards maintenance, with the six-banger, as compared to the turbo 4-cyl, there are fewer components, less plumbing, fewer sensors (and wiring), and so forth.  It's a vastly simpler system.  The less there is, the less there is to break down.

Most folks don't know that the Subaru turbos have replaceable banjo-type oil fittings.  These fittings have super-fine filtering screens within them. Assuming syn oil used in turbos, then these super fine banjo fittings need to be replaced at each and every oil change.  Dino oil, every other oil change, since oil change is sooner.   The fittings are NOT expensive, but since most owners don't know that they are even there, and since some dealerships cut corners, they don't get replaced on a regular basis, and turbo failure occurs.  If you're lucky he turbo failure will not damage the rest of your engine.

Long story short, and not to pick on Subaru tubos, because there are many worse, the old saying that "There is no replacement for displacement" is still true.   

I have said, for a long time in turbo-related threads, then when turbo engines are available with thermostatically-controlled oil coolers (directly connected to forced turbo oil feed), AND forced water cooling for turbo  housing, then I will consider buying them.  Until then, I'll pass, as they are not done right, in my opinion.  They run too hot, and for no good reason except that many manufacturers think it easier, and cheaper to make turbo engines on the cheap, instead of doing it right.  As a former Pro mechanic, I've replaced a few failed turbos, many makes,  and also told the owners of turbo engines, again many makes,  that their turbo had grenaded, and ruined their engine.  YMMV.

It's all right to be tired and miss something.  Do it all the time, myself.  That's why I have to edit so many of my posts, AND reply on account of my mistakes on my original posts.  BTDT.
