Very sure footed, amazing in snow and rain
Brakes warped from almost new
AC is marginal
Gas mileage ain't great

'05 WRX bought new and kept 18 mo. for these reasons.
Also attracts subie dorks with their vape pens
High miles? Have the owner start it from dead cold while you watch the exhaust. If you see or smell smoke it's probably burning oil. I was about to say from the valve stem seals but gtgto beat me to it :)
