They should still make Corolla wagons. I'd get another. Ten years, 212000 miles, the only problem is oil burning - I just use thicker viscosity. I've done only minor repairs from wear and tear. Original clutch and exhaust - amazing considering winter driving. The reliability, efficiency, and practicality of this car should be emulated. I average 42 mpg summer, 34 mpg winter, overall 38 mpg. I don't baby this car - I don't slow down for speed bumps, I use it like a pick-up (firewood, cement, loam, etc.), I carry people, luggage, doors, trees from the nursery... I fear this one is irreplaceable. Toyota should return to making the Corolla wagon. Try it as a hybrid, or at least with very low emissions. For now, if I had to replace this, it'd be with a Focus.
As above - reliability, practicality - and at this stage, it's almost free to own.
