I have a 1998 Subaru Legacy GT with 243,000 km on the engine. The car is in mint condition - arctic white paint. The head gasket now needs to be replaced. Did all the maintenance. I've been lucky it lasted this long. Car was mostly highway driven. Car is drivable and the leaking coolant is gradual and would go un-noticed to someone not familiar with the car. Head gasket is not reliable so getting it replaced by a certified Subaru mechanic. Will cost $3,500 to do it right. Don't recommend to do it cheaply because if its not done right the gasket can leak again.

This wagon is unsuspecting, with the 2.5l engine this car has some nice giddy up to blow past Prius's and Honda's. Short comings would be the notorious head gasket issue and cup holder placement. Fuel economy is not great, but with a 90's car with awd what do you expect? The benefits being an excellent awd system and plenty of room. With the ability to floor the gas or slam on the brakes and getting 0 wheel slippage in the pouring rain allows for a confident feel behind the wheel in any driving conditions.
The 1998 Subaru Legacy wagon that I had bought for a 2nd car, gave us nothing but trouble. So glad I got rid of it...it was nothing but a money pit. Oil leaks, gaskets, brakes, air conditioner problems, and then finally what broke the camels back transmission problems!!!!!
This in my opinion "midsized" sedan is a heavy, heavy beast, that you will LOVE to drive. Extremely stout, excellent in rain sleet snow or shine, I've put 170,000 miles on mine with only one issue, head gaskets. Thats not as bad as it sounds. 800 dollars at 120k and going FINE for another 50k... so far! Also handles like a dream. My previous car was a fully loaded eagle talon tsi awd. I thought that handled well and i had it lowered! This car puts it to shame. I have nothing but good to say about my legacy. I regularly get 28mpg... 40% city 60% highway. They also look great with some 17" wheels and a slight height drop.
Although a plain vanilla car, reliability has been outstanding. Only major repair was new alternator at 100,000. Otherwise, vehicle still going strong at over 112,000 miles. Just wish they'd pep up the styling for this model to compete with the Europeans.
