I purchased my '01 Focus Wagon SE from a dealership in 2011 with ~190,000 mi on it for $2850. It has been almost 2 years now and this car has given me almost no grief.
The A/C went out once (A/C is a luxury anyways, who cares?), front coil springs had to be replaced, and the muffler hit the ground once while going over a speed bump (temporarily fixed it with shoelaces, haha)
All in all, great performance; great value!
I would prefer larger rims/tires (scraped the underneath of the vehicle going on a slightly-uneven gravel road--ouch!), and also wish the interior was a little more friendly for tall folks (it was somewhat hard to get comfortable driving when I first purchased this vehicle).
