I've drivin subaru's since I started driving. My family had a 76' 1800 sedan, 81' dl wagon, 87' dl wagon, 89' dl wagon, 91' legacy wagon, and I have now owned a wrx and an sti. Subarus last a very long time with regular maintenance we actually got 425k out of the 81 wagon before my mother gave it away and all the others passed the 200 thousand mark so the reliability of a subaru is definitely on a favorable side.

 

well, I think the STi is much different from previous subarus.

1) they dont build them like they used to.
2) its a relatively high pressure turbo engine
3) the way an sti is driiven is alot more aggressive than the 81 wagon that lasted 425k I am assuming... otherwise why buy a turbo car with 300hp.... not to utilize the power? i didnt think so

I think these cars will safely hit 100+K miles, but dont expect them to last forever like the older ones did...

 

Usually on boosted cars, the head gasket will probably need to be changed out at around 100k.

 

With a high performance vehicle longevity is also a product of how much power you use and how much money you wish to put into it

Besides the engine there are things that wear out like brakes, tires, and pads.

 

I think we all know that if you drive a car hard its obviously going to have a shorter life, but wrxchris asked about normal driving.

 

Not sure how much they cost. Maybe someone else here can help you with that. It's not like when your odometer hits 100k, you have to change it. My friend had to change his gaskets at 130k. It can vary from car to car. All I'm saying is that start to get ready at around 100k.

 

There's no reason he should ever have to change his head gaskets, they aren't exactly wear components like clutches and brakes. Usually things like overheating cause them to need replacing, so that shouldn't be a concern at all. The only reasons the past EJ25s had head gasket problems is because the actual head gaskets weren't designed well and Subaru learned from that problem and corrected it.

Since USDM STis haven't been around long enough, it's too soon to know if they have any long term issues. For example, the SVX's trannies didn't start breaking until 80k miles. I'm willing to bet, however, that with the proper maintenance, an STi that isn't tracked weekly or abused in any way would make it past 100k miles without many problems.

 

This isn't really an answerable question because the sti and wrx haven't been round long enough

 

Just not in the states they haven't

I think a wrx can be found since 92 in japan.
