Hi there. I've owned 8 Subaru GL's from 1985 to 1999 (they rust terribly here in the midwest and my wife was rear ended in at least 3 of them).
So, I was just putzing around Craigslist, and on a lark - I put Subaru GL in the search function.
Up sprang a 1984 GL in Yakima, Washington. I made arrangements immediately to buy it (the seller actually responded to me and held onto the car for me). 3 days later, I was in Yakima picking the car up.
The condition is stunning - just some surface rust on the rear liftgate and around the bottom of the doors (those will be fixed within the next 2 months). There is a slight oil leak (I had to put 1 quart in over the 2,100 miles I drove). It has a 5 speed (the stick just needs to be tightened up), crank windows, stock stereo (all 4 speakers work), A/C, and a pretty clean interior. The headliner is fine, it just needs to be refreshed (some fading). It drove great through the mountains (I only had to put it into 3rd twice). I even hit a piece of a truck in the road (it was night & 4 different cars hit the same thing), so I used AAA to bring it to a tire shop in Wyoming. Both steel wheels were damaged, but I happened to find the only 13" wheels for this car at a local junk yard (nobody had these wheels for a 5 state area), so I was extremely lucky. Even better, were that these were alloys off of a 1989 GL10. I then took it to a Discount Tire in Cheyenne (which was on my route to Illinois) and wouldn't you know it - they had a set of four 13" tires (P175/70 R13).... & they were in stock no less. The alloys cost me $100, and the tires cost me $280 installed with a road hazard warranty.
I then got to Illinois without any issues.
I averaged 30 mpg over the whole trip (while averaging 70 mph). In the mountains, it was 24 mpg - on the flat road, it was 34 mpg. The fastest I took the car was 85 mph.
Not bad for a 35 year old car with 255,000 miles.
