Couldn't believe my eyes yesterday on I-5 Southbound approaching the Columbia River: two pickups trailering a total of four 1st (one could have been 2nd) Generation Subaru's.
Called the LEONE (or, LOYALE later in the US) Series, they are about the equivalent of a VW Bug as far as simplicity and durability was concerned. These are highly prized in the backwoods of Idaho, Eastern WA, etc. as they are almost unstoppable in the snow ( 1,700 lbs. curb weight may have something to do with it). Even the 2WD versions do very well.
These were very, very rough examples, a couple of them looked like they had been wrecked and parked for 20 years, or so.
But, underneath, a veritable treasuretrove of mechanical parts, presumeably driveline-related, for the right enthusiast. They got great gas mileage, too!
Cheers!
p.s. re: the OP - I'd look for a good running $3K Subaru and keep $2K for parts, etc. They all are really good in the winter. As for the "performance" part, either up the $ or drop your expectations to performing well in the snow.
