Be aware that almost every company has their "throwaway" model! I was a service tech at a Toyota dealership in the early 90s, and I can tell you, the final series of the tercel was crap on wheels! During cold weather, every tech in the shop had at least 3 of them in the back lot waiting for the heads to come back from the machine shop. I did so many that I could have the head off and stripped (including pulling the valves) and ready to go to the machine shop in less than an hour! As troublesome as that engine was, they used it in at least two other models afterwards. Oh yeah, the lowest mileage I heard of for the tercelitis (yes, we had a nickname for it!) was around 25,000 miles. I have tried to warn several people away from those models, but people will do what they will do.
