I bought my Ranger new in 1993. I now have over 200K miles. I learned how to drive a manual with it and it still has the original clutch and tranny. I do most of the routine maintenance myself. Most of it is fairly easy except for the spark plugs (the engineers must have had very small hands). The only real problem I have had was the computer would randomly open the fuel pump relay. New computer, problem solved. The engine doesn't leak oil, but I've been going through some coolant. It doesn't show up in the oil, so it must not be a real problem. The gas mileage isn't as good as when I got it, but it's still better than most other trucks (20-25 avg).
Solid engine and tranny. If you take care of it it will last a long time. Ice cold ac. very reliable truck.
No tach. The 4-cylinder will keep on going, but you won't get there really fast. More cab room especially on passenger side. Has stiff clutch.
