Well I have driven about 750 km on it, within the city and on the highway abit. It seems both of the front wheels really wear on the outside real bad. And if I crank the wheel all the way one way, one wheel rubs on something real bad (front drivers). Down to the wires on the one wheel now. I figure I can go through tires from pick and pull for $15 a hit. I have 2 tires on rims in the trunk. Man i hate unibodies, you are right, these things are unibody. I guess I drive it the way it is until it dies. Filled up for $25 goes about 350km, not bad.
