Faults:
Radiator.
Torque bind.
Major oil leaks onto the catalytic converter resulting in scary, but harmless smoke from the engine bay.
Crankshaft problems, resulting in bad timing and terrible MPG, slow acceleration, have to floor it to move. It's drivable, but its days are numbered. I expected more from the 2.2L engine, it appears half-dead at 150K miles.
It's possible someone had worked on it and didn't tighten the crankshaft bolt all the way, resulting in it getting loose and damaging the key.
General Comments:
I don't like frameless windows.
The interior is cheap. The seats are not too bad but could be better.
Brighton is the cheapest they have, doesn't even come with a tach.
Theoretically, a "L" Legacy can be reliable with 2.2L / 5 speed, but this particular auto was apparently abused, and at 150K miles didn't look too good.
Someone apparently put mismatched tires at one point and it resulted in torque bind. If you drive around in tight circles, the car will vibrate, which is solid evidence of torque bind. Had to take a piece off the transmission, grind it to make it smooth again.
On the plus side, it handles OK, grips the road.
All in all, it's basic transportation, nothing fancy, an economy car. If treated well, it should probably run well.
Supposedly the older 2.2L is a lot more reliable than 2.5L with head gasket issues, though in my experience, I haven't found 2.2L to be all that reliable.
It has major oil leaks in several places, dripping onto the cat converter, resulting in very scary but harmless smoke coming from the engine bay at stoplights.
