As the car is out of extended warranty, I am about to start doing my own basic servicing and maintenance. I want to get a torque wrench, but having opened my Sealy catalogue and seen the plethora of different handle lengths and torque ranges, I would appreciate some advice. i am unlikely to be stripping the engine, just the basics of servicing and brake replacement. As my socket set has 3/8" and 1/2" ratchets I will go with either of those. Then the choice is a variety of handle lengths (275mm to 1070mm) and a huge number of overlapping torque ranges. My guess is 40Nm to 200Nm, but thats quite a range and therefore expensive. Would a narrower range be adequate or ultimately a false economy?
