Congratulations on your purchase! I am also very methodical when it comes to buying used vehicles. I consider it like hunting. The fun is in the preparation, anticipation, and the details. Once it all comes together and you pull the trigger, all that is over and it is on to the next 'trophy'.
A word of caution on that torque wrench... I used an old Craftsman dial and click type for 20+ years. I finally broke down and bought myself one very similar to this one you bought. I loved it every time I used it but probably a year after purchase, I opened the battery compartment and found the batteries had corroded everything inside there. It was ruined and became a $100+ piece of garbage. I am back to using my old Craftsman. Learn from my mistake. Pull the batteries when you are storing it.
